Are you using Cygwin or Mingw32? It looks like you're using Cygwin
examples with Mingw32 compiler.

I just realized that the GNU Makefile was written for Cygwin and 
won't work with Mingw32. To make it work with Mingw32, *remove*
the `--entry __cygwin_noncygwin_dll_entry AT 12' from the DLLWRAP_FLAGS
variable and rebuild.
