2001-02-21 Tor Lillqvist <tml@iki.fi> Cygwin support contributed by Stefan Ondrejicka <ondrej@idata.sk>. Hopefully I got it all in while simultaneously adding support for auto*/libtool for mingw. * Makefile.am: Changes for auto* support on Cygwin and Win32. Do still distribute the hand-written makefiles and *.win32.in files, though. Use GIO, GSPAWN and PLATFORMDEP macros set by configure. Use -no-undefined. Pass -export-symbols glib.def to libtool. * configure.in: Define G_PLATFORM_WIN32 on both pure Win32 (mingw) and Cygwin. Add AC_CYGWIN, AC_EXEEXT and AC_LIBTOOL_WIN32_DLL calls for Cygwin and mingw support. Check for %I64u guint64 format (in MS C library). Set G_MODULE_IMPL on mingw and Cygwin. Use ac_object and ac_exeext. Set GIO, GSPAWN, PLATFORMDEP and G_LIBS_EXTRA. Compile timeloop only on Unix. Define OS_WIN32 automake conditional on Win32. * glib.h: Include gwin32.h also on Cygwin. * gfileutils.c (get_contents_posix): Use O_BINARY (defined as 0 on Unix) for Cygwin's sake. * gtimer.c (GETTIME): Reduce #ifdefs, use a macro GETTIME(). * gconvert.c * gthread.c * gutf8.c * gutils.c: For code needed both on Cygwin and native Win32, test for G_PLATFORM_WIN32. * gmarkup.h: Use G_BEGIN_DECLS and G_END_DECLS. * gtypes.h: Refine GLIB_VAR definition. Also check for DLL_EXPORT in case compiling a static library on Win32 or Cygwin. * gwin32.c: No <direct.h> on Cygwin. No need for ftruncate() or dirent emulation on Cygwin. (get_package_directory_from_module) Convert return value from GetModuleFileName() to POSIX path on Cygwin. * tests/Makefile.am (progs_LDADD): Link with libglib, libgthread and libgmodule as appropriate. Use -no-undefined. * gbacktrace.c: Move #ifdefs around a bit on Win32. * gshell.c (unquote_string_inplace): Make static.
