Oops, actually commit the configure.in change I thought I did in my

previous commit:

2001-09-26  Tor Lillqvist  <tml@iki.fi>

	* configure.in: Retract my change earlier today. Don't preset
	autoconf variables in a try to match both mingw and MSVC. Instead,
	he who packages a prebuilt GLib developer distribution for Win32
	runs configure twice: once for mingw, once for MSVC, and then uses
	diff -D on the glibconfig.h files to generate a suitably ifdeffed
	glibconfig.h for distribution that suits both compilers. (Ditto
	for config.h, although that file wouldn't be distributed in a
	developer package, but in a source package for Win32 users who
	want to build GLib but can't use configure.)
