/* PCRE2 is written in Standard C, but there are a few non-standard things it
can cope with, allowing it to run on SunOS4 and other "close to standard"
systems.

In environments that support the GNU autotools, config.h.in is converted into
config.h by the "configure" script. In environments that use CMake,
config-cmake.in is converted into config.h. If you are going to build PCRE2 "by
hand" without using "configure" or CMake, you should copy the distributed
config.h.generic to config.h, and 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,
but if you do, default values will be taken from config.h for non-boolean
macros that are not defined on the command line.

Boolean macros such as HAVE_STDLIB_H and SUPPORT_PCRE2_8 should either be
defined (conventionally to 1) for TRUE, and not defined at all for FALSE. All
such macros are listed as a commented #undef in config.h.generic. Macros such
as MATCH_LIMIT, whose actual value is relevant, have defaults defined, but are
surrounded by #ifndef/#endif lines so that the value can be overridden by -D.

PCRE2 uses memmove() if HAVE_MEMMOVE is defined; otherwise it uses bcopy() if
HAVE_BCOPY is defined. If your system has neither bcopy() nor memmove(), make
sure both macros are undefined; an emulation function will then be used. */

/* By default, the \R escape sequence matches any Unicode line ending
   character or sequence of characters. If BSR_ANYCRLF is defined (to any
   value), this is changed so that backslash-R matches only CR, LF, or CRLF.
   The build-time default can be overridden by the user of PCRE2 at runtime.

/* If you are compiling for a system that uses EBCDIC instead of ASCII
   character codes, define this macro to any value. When EBCDIC is set, PCRE2
   assumes that all input strings are in EBCDIC. If you do not define this
   macro, PCRE2 will assume input strings are ASCII or UTF-8/16/32 Unicode. It
   is not possible to build a version of PCRE2 that supports both EBCDIC and
   UTF-8/16/32. */
