7 years ago Fuller exception from some recent testing of mine. Looks like pain shutil.rmtree() isn't enough, and we might have to do a pass through to force write permissions on files (on POSIX, write permission to the directory would be enough, sigh).

The build process fails when cleaning up the temporary directory if contained files do not have write permissions.
This can be seen by building gedit.cfg under msys 20161025 which fails when removing fakepq.h which only has permissions r--r--r--.
