If you want to build Cygwin applications, you shouldn't. Those are for
"native" Win32, not Cygwin. (But read on.)

The pkg-config program has been especially enhanced to take care of
this. When compiled for Win32 (*not* if compiled for Cygwin, which is
just a particular kind of Unix), it automatically replaces the
"prefix" variable in .pc filles with the actual prefix deduced at
run-time from the location of the .pc file.

If you are using -mno-cygwin, then those runtime and developer
packlages you downloaded should be OK. But on the other hand, then you
shouldn't install them in /usr/lib, which is for Cygwin stuff only.

You need to have the libs after the C files on the compiler command
line. Try this:

gcc -mno-cygwin -mms-bitfield `pkg-config --cflags gtk+-2.0` -o hello-gtk hello-gtk.c `pkg-config --libs gtk+-2.0`
