[glib/wip/pwithnall/962-drop-embedded-pcre: 2/5] subprojects: Add libpcre.wrap

[Philip Withnall <pwithnall src gnome org>]

commit c19c72c59ef61d91ef477871c4537e77c0b26d45
Author: Philip Withnall <pwithnall endlessos org>
Date:   Wed Jun 9 12:22:54 2021 +0100

    subprojects: Add libpcre.wrap
    
    This is from the wrapdb, but with the 8.37-1 wrapdb patch expanded into
    a patch directory. The following commit will add the changes needed for
    this subproject to work correctly in GLib.
    
    Eventually, it would be nice if those changes would move into the
    wrapdb, but that depends on what the wrapdb maintainers think of
    https://github.com/mesonbuild/pcre/pull/4.

+
+
+/* PCRE 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 PCRE "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_PCRE8 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.
+
+PCRE 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 PCRE at runtime. */

+/* If you are compiling for a system that uses EBCDIC instead of ASCII
+   character codes, define this macro to any value. You must also edit the
+   NEWLINE macro below to set a suitable EBCDIC newline, commonly 21 (0x15).
+   On systems that can use "configure" or CMake to set EBCDIC, NEWLINE is
+   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
+   a version of PCRE that supports both EBCDIC and UTF-8/16/32. */
