Older versions of gcc on windows32 (before egcs-1.1.2) didn't link
with libuser32.a by default, and that's what you're seeing.

Solution:
  1. upgrade to gcc-2.95.2
  2. Link with -luser32 explicitly.
     
     $ gcc -o foo foo.c -luser32

There have two binary releases (gcc-2.95 and gcc-2.95.2), and I do 
recommend that you upgrade.
