I briefly considered trying to get a GTK/OpenGL application to work on Windows. In theory that should have been easy, since GTK and OpenGL are supposed to be portable, and I wasn't doing anything OS-specific.
Windows POSIX layer put a stop to that pretty quickly. I used popen (which Window's POSIX compatibility layer includes) to write frames of video out to an external process, but on Linux that required that I handle SIGPIPE, and Windows' emulation of POSIX signal handling was woefully incomplete. Code that worked fine on Linux wouldn't build against Windows' implementations of signal (I think Windows didn't even define SIGPIPE as a constant).
