	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.

	* 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.
