Tor, I added a section in the README of my GTK+ application that instructs MSYS users to edit their copy of gtk+-2.0.pc, and add in the missing -mwindows option. After that change, the build process on MSYS is the same as it is on all other platforms. This solves my problem. If you write an FLTK application on Linux, and follow the FLTK documentation on how to write build files, the build process for your application is identical on all platforms. I believe we should strive to give GTK+ application developers the same experience.
