Trouble Compiling GLib 2.6.2 on Win98

[Jeffery To <jeffery to gmx net>]

Hi,

I'm trying to compile GLib 2.6.2, as a prelude to compiling GTK+, on 
Windows 98 (I know, not a very good idea), and I'm running into this error:

if /bin/bash ../libtool --mode=compile gcc -mcpu=pentium3 
-DHAVE_CONFIG_H -I. -I. -I.. -DG_LOG_DOMAIN=\"GLib-GObject\" -I.. 
-I../glib -I.. -DG_DISABLE_CAST_CHECKS -DG_DISABLE_DEPRECATED 
-DGOBJECT_COMPILATION -DG_DISABLE_CONST_RETURNS  -I/local/include   -O3 
-mms-bitfields -Wall -MT gobject.lo -MD -MP -MF ".deps/gobject.Tpo" \
  -c -o gobject.lo `test -f 'gobject.c' || echo './'`gobject.c; \
then mv -f ".deps/gobject.Tpo" ".deps/gobject.Plo"; \
else rm -f ".deps/gobject.Tpo"; exit 1; \
fi

I'm using gcc from MinGW in a Cygwin environment. Any help will be 
appreciated.

Thanks,
