can cope with, allowing it to run on SunOS4 and other "close to standard"
systems.
In environments that support the facilities, config.h.in is converted by
"configure", or config-cmake.h.in is converted by CMake, into config.h. If you
are going to build PCRE "by hand" without using "configure" or CMake, you
should copy the distributed config.h.generic to config.h, and then edit the
macro definitions to be the way you need them. You must then add
-DHAVE_CONFIG_H to all of your compile commands, so that config.h is included
at the start of every source.
Alternatively, you can avoid editing by using -D on the compiler command line
to set the macro values. In this case, you do not have to set -DHAVE_CONFIG_H.
PCRE uses memmove() if HAVE_MEMMOVE is set to 1; otherwise it uses bcopy() if
HAVE_BCOPY is set to 1. If your system has neither bcopy() nor memmove(), set
them both to 0; an emulation function will be used. */

automatically adjusted. When EBCDIC is set, PCRE assumes that all input
strings are in EBCDIC. If you do not define this macro, PCRE will assume
input strings are ASCII or UTF-8/16/32 Unicode. It is not possible to build

/* Public options. Some are compile-time only, some are run-time only, and some
are both. Most of the compile-time options are saved with the compiled regex so
that they can be inspected during studying (and therefore JIT compiling). Note
that pcre_study() has its own set of options. Originally, all the options
defined here used distinct bits. However, almost all the bits in a 32-bit word
are now used, so in order to conserve them, option bits that were previously
only recognized at matching time (i.e. by pcre_exec() or pcre_dfa_exec()) may
also be used for compile-time options that affect only compiling and are not
relevant for studying or JIT compiling.
Some options for pcre_compile() change its behaviour but do not affect the
behaviour of the execution functions. Other options are passed through to the
execution functions and affect their behaviour, with or without affecting the
behaviour of pcre_compile().
Options that can be passed to pcre_compile() are tagged Cx below, with these
variants:
C1 Affects compile only
C2 Does not affect compile; affects exec, dfa_exec
C3 Affects compile, exec, dfa_exec
C4 Affects compile, exec, dfa_exec, study
C5 Affects compile, exec, study
Options that can be set for pcre_exec() and/or pcre_dfa_exec() are flagged with
E and D, respectively. They take precedence over C3, C4, and C5 settings passed
from pcre_compile(). Those that are compatible with JIT execution are flagged
with J. */

/* When compiling a DLL for Windows, the exported symbols have to be declared
using some MS magic. I found some useful information on this web page:
http://msdn2.microsoft.com/en-us/library/y4h7bcy6(VS.80).aspx. According to the
information there, using __declspec(dllexport) without "extern" we have a
definition; with "extern" we have a declaration. The settings here override the
setting in pcre.h (which is included below); it defines only PCRE_EXP_DECL,
which is all that is needed for applications (they just import the symbols). We
use:
PCRE_EXP_DECL for declarations
PCRE_EXP_DEFN for definitions of exported functions
PCRE_EXP_DATA_DEFN for definitions of exported variables
The reason for the two DEFN macros is that in non-Windows environments, one
does not want to have "extern" before variable definitions because it leads to
compiler warnings. So we distinguish between functions and variables. In
Windows, the two should always be the same.
The reason for wrapping this in #ifndef PCRE_EXP_DECL is so that pcretest,
which is an application, but needs to import this file in order to "peek" at
internals, can #include pcre.h first to get an application's-eye view.
In principle, people compiling for non-Windows, non-Unix-like (i.e. uncommon,
special-purpose environments) might want to stick other stuff in front of
exported symbols. That's why, in the non-Windows case, we set PCRE_EXP_DEFN and
PCRE_EXP_DATA_DEFN only if they are not already set. */

/* PCRE keeps offsets in its compiled code as 2-byte quantities (always stored
in big-endian order) by default. These are used, for example, to link from the
start of a subpattern to its alternatives and its end. The use of 2 bytes per
offset limits the size of the compiled regex to around 64K, which is big enough
for almost everybody. However, I received a request for an even bigger limit.
For this reason, and also to make the code easier to maintain, the storing and
loading of offsets from the byte string is now handled by the macros that are
defined here.
The macros are controlled by the value of LINK_SIZE. This defaults to 2 in
the config.h file, but can be overridden by using -D on the command line. This
is automated on Unix systems via the "configure" command. */

fastest code (no loop, no memory access), and there are several places in the
interpreter code where this happens. In order to ensure that all the case lists
remain in step, we use macros so that there is only one place where the lists
are defined.
These values are also required as lists in pcre_compile.c when processing \h,
\H, \v and \V in a character class. The lists are defined in pcre_tables.c, but
macros that define the values are here so that all the definitions are
together. The lists must be in ascending character order, terminated by
NOTACHAR (which is 0xffffffff).
Any changes should ensure that the various macros are kept in step with each
other. NOTE: The values also appear in pcre_jit_compile.c. */

/* If PCRE is to support UTF-8 on EBCDIC platforms, we cannot use normal
character constants like '*' because the compiler would emit their EBCDIC code,
which is different from their ASCII/UTF-8 code. Instead we define macros for
the characters so that they always use the ASCII/UTF-8 code when UTF-8 support
is enabled. When UTF-8 support is not enabled, the definitions use character
literals. Both character and string versions of each character are needed, and
there are some longer strings as well.
This means that, on EBCDIC platforms, the PCRE library can handle either
EBCDIC, or UTF-8, but not both. To support both in the same compiled library
would need different lookups depending on whether PCRE_UTF8 was set or not.
This would make it impossible to use characters in switch/case statements,
which would reduce performance. For a theoretical use (which nobody has asked
for) in a minority area (EBCDIC platforms), this is not sensible. Any
application that did need both could compile two versions of the library, using
macros to give the functions distinct names. */

/* UTF-8 support is not enabled; use the platform-dependent character literals
so that PCRE works in both ASCII and EBCDIC environments, but only in non-UTF
mode. Newline characters are problematic in EBCDIC. Though it has CR and LF
characters, a common practice has been to use its NL (0x15) character as the
line terminator in C-like processing environments. However, sometimes the LF
(0x25) character is used instead, according to this Unicode document:
http://unicode.org/standard/reports/tr13/tr13-5.html
PCRE defaults EBCDIC NL to 0x15, but has a build-time option to select 0x25
instead. Whichever is *not* chosen is defined as NEL.
In both ASCII and EBCDIC environments, CHAR_NL and CHAR_LF are synonyms for the

check_escape(). There are two tests in the code for an escape
greater than ESC_b and less than ESC_Z to detect the types that may be

code vector run on as long as necessary after the end. We store an explicit
offset to the name table so that if a regex is compiled on one host, saved, and
then run on another where the size of pointers is different, all might still
be well.
The size of the structure must be a multiple of 8 bytes. For the case of
compiled-on-4 and run-on-8, we include an extra pointer that is always NULL so
that there are an even number of pointers which therefore are a multiple of 8
bytes.
It is necessary to fork the struct for the 32 bit library, since it needs to
use pcre_uint32 for first_char and req_char. We can't put an ifdef inside the
typedef because pcretest needs access to the struct of the 8-, 16- and 32-bit
variants.
*** WARNING ***
When new fields are added to these structures, remember to adjust the code in
pcre_byte_order.c that is concerned with swapping the byte order of the fields
when a compiled regex is reloaded on a host with different endianness.
*** WARNING ***
There is also similar byte-flipping code in pcretest.c, which is used for
testing the byte-flipping features. It must also be kept in step.
*** WARNING ***

for example, to link from the start of a subpattern to its alternatives and its
end. The use of 16 bits per offset limits the size of an 8-bit compiled regex
to around 64K, which is big enough for almost everybody. However, I received a
request for an even bigger limit. For this reason, and also to make the code
easier to maintain, the storing and loading of offsets from the compiled code

are defined.
These values are also required as lists in pcre2_compile.c when processing \h,

/* If PCRE2 is to support UTF-8 on EBCDIC platforms, we cannot use normal
character constants like '*' because the compiler would emit their EBCDIC code,
which is different from their ASCII/UTF-8 code. Instead we define macros for
the characters so that they always use the ASCII/UTF-8 code when UTF-8 support
is enabled. When UTF-8 support is not enabled, the definitions use character
literals. Both character and string versions of each character are needed, and
there are some longer strings as well.
This means that, on EBCDIC platforms, the PCRE2 library can handle either
EBCDIC, or UTF-8, but not both. To support both in the same compiled library
would need different lookups depending on whether PCRE2_UTF was set or not.
This would make it impossible to use characters in switch/case statements,
which would reduce performance. For a theoretical use (which nobody has asked
for) in a minority area (EBCDIC platforms), this is not sensible. Any
application that did need both could compile two versions of the library, using
macros to give the functions distinct names. */

/* UTF-8 support is not enabled; use the platform-dependent character literals
so that PCRE2 works in both ASCII and EBCDIC environments, but only in non-UTF
mode. Newline characters are problematic in EBCDIC. Though it has CR and LF
characters, a common practice has been to use its NL (0x15) character as the
line terminator in C-like processing environments. However, sometimes the LF
(0x25) character is used instead, according to this Unicode document:
http://unicode.org/standard/reports/tr13/tr13-5.html
PCRE2 defaults EBCDIC NL to 0x15, but has a build-time option to select 0x25
instead. Whichever is *not* chosen is defined as NEL.

like \N.
Negative numbers are used to encode a backreference (\1, \2, \3, etc.) in
check_escape(). There are tests in the code for an escape greater than ESC_b

types that consume characters. If any new escapes are put in between that don't
