This is needed for ctypes.util.find_library().

In 3.7, there is a compiled binding, and so the -devel dependency was dropped. Also, pkgconf will soon be providing and replacing pkg-config, which will cause the glib2.0 dependency to be dropped. -- Yaakov -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
