-Compiling PCRE on non-Unix systems
-----------------------------------
-
-See below for comments on Cygwin or MinGW usage. I (Philip Hazel) have no
-knowledge of Windows sytems and how their libraries work. The items in the
-PCRE Makefile that relate to anything other than Unix-like systems have been
-contributed by PCRE users. There are some other comments and files in the
-Contrib directory on the ftp site that you may find useful.
-
-The following are generic comments about building PCRE:
-
-If you want to compile PCRE for a non-Unix system (or perhaps, more strictly,
-for a system that does not support "configure" and make files), note that PCRE
-consists entirely of code written in Standard C, and so should compile
-successfully on any machine with a Standard C compiler and library, using
-normal compiling commands to do the following:
-
-(1) Copy or rename the file config.in as config.h, and change the macros that
-define HAVE_STRERROR and HAVE_MEMMOVE to define them as 1 rather than 0.
-Unfortunately, because of the way Unix autoconf works, the default setting has
-to be 0. You may also want to make changes to other macros in config.h. In
-particular, if you want to force a specific value for newline, you can define
-the NEWLINE macro. The default is to use '\n', thereby using whatever value
-your compiler gives to '\n'.
-
-(2) Copy or rename the file pcre.in as pcre.h, and change the macro definitions
-for PCRE_MAJOR, PCRE_MINOR, and PCRE_DATE near its start to the values set in
-configure.in.
-
-(3) Compile dftables.c as a stand-alone program, and then run it with
-the single argument "chartables.c". This generates a set of standard
-character tables and writes them to that file.
-
-(4) Compile maketables.c, get.c, study.c and pcre.c and link them all
-together into an object library in whichever form your system keeps such
-libraries. This is the pcre library (chartables.c is included by means of an
-#include directive). If your system has static and shared libraries, you may
-have to do this once for each type.
-
-(5) Similarly, compile pcreposix.c and link it (on its own) as the pcreposix
-library.
-
-(6) Compile the test program pcretest.c. This needs the functions in the
-pcre and pcreposix libraries when linking.
-
-(7) Run pcretest on the testinput files in the testdata directory, and check
-that the output matches the corresponding testoutput files. You must use the
--i option when checking testinput2. Note that the supplied files are in Unix
-format, with just LF characters as line terminators. You may need to edit them
-to change this if your system uses a different convention.
-
-If you have a system without "configure" but where you can use a Makefile, edit
-Makefile.in to create Makefile, substituting suitable values for the variables
-at the head of the file.
-
-Some help in building a Win32 DLL of PCRE in GnuWin32 environments was
-contributed by Paul Sokolovsky. These environments are Mingw32
-(http://www.xraylith.wisc.edu/~khan/software/gnu-win32/) and CygWin
-(http://sourceware.cygnus.com/cygwin/). Paul comments:
-
-  For CygWin, set CFLAGS=-mno-cygwin, and do 'make dll'. You'll get
-  pcre.dll (containing pcreposix also), libpcre.dll.a, and dynamically
-  linked pgrep and pcretest. If you have /bin/sh, run RunTest (three
-  main test go ok, locale not supported).
-
-Changes to do MinGW with autoconf 2.50 were supplied by Fred Cox
-<sailorFred@yahoo.com>, who comments as follows:
-
-  If you are using the PCRE DLL, the normal Unix style configure && make &&
-  make check && make install should just work[*]. If you want to statically
-  link against the .a file, you must define PCRE_STATIC before including
-  pcre.h, otherwise the pcre_malloc and pcre_free exported functions will be
-  declared __declspec(dllimport), with hilarious results.  See the configure.in
-  and pcretest.c for how it is done for the static test.
-
-  Also, there will only be a libpcre.la, not a libpcreposix.la, as you
-  would expect from the Unix version. The single DLL includes the pcreposix
-  interface.
-
-[*] But note that the supplied test files are in Unix format, with just LF
-characters as line terminators. You will have to edit them to change to CR LF
-terminators.
-
-A script for building PCRE using Borland's C++ compiler for use with VPASCAL
-was contributed by Alexander Tokarev. It is called makevp.bat.
-
-These are some further comments about Win32 builds from Mark Evans. They
-were contributed before Fred Cox's changes were made, so it is possible that
-they may no longer be relevant.
-
-"The documentation for Win32 builds is a bit shy.  Under MSVC6 I
-followed their instructions to the letter, but there were still
-some things missing.
-
-(1) Must #define STATIC for entire project if linking statically.
-    (I see no reason to use DLLs for code this compact.)  This of
-    course is a project setting in MSVC under Preprocessor.
-
-(2) Missing some #ifdefs relating to the function pointers
-    pcre_malloc and pcre_free.  See my solution below.  (The stubs
-    may not be mandatory but they made me feel better.)"
-
-=========================
-#ifdef _WIN32
-#include <malloc.h>
-
-void* malloc_stub(size_t N)
-{ return malloc(N); }
-void free_stub(void* p)
-{ free(p); }
-void *(*pcre_malloc)(size_t) = &malloc_stub;
-void  (*pcre_free)(void *) = &free_stub;
-
-#else
-
-void *(*pcre_malloc)(size_t) = malloc;
-void  (*pcre_free)(void *) = free;
-
-#endif
