When I compile a GTK+ application in Cygwin, all the GTK externals are 
unresolved.  Output from pkg-config and the /usr/lib directory look fine, and 
are included below along with the linkage errors and the source program.

I downloaded and installed Cygwin last week.

I have compiled and run this little program on Slackware without any problem.

Why are the GTK externals going unresolved on Cygwin?

Thanks,
   Ollie
