The included files are written with the wrong version if the intended version is 800 or 620, and GM hangs when trying to read the generated .gmk file. Not sure why this causes GM to hang, maybe GM itself is buggy at that point and just doesn't expect data in the old version format. Anyway, patch is linked below.

Thank you. Implemented in r493. GM hangs because it reads incorrect zlib data. The zlib library actually hangs, which causes LGM to hang sometimes too. We have a bug open about it here:
