mpatch: use int rather than ssize_t We might need to be more clever than this to make Py2.5 happy.

osutil: improve portability - manually inline mode_to_kind - remove unused alloca include - remove fstatat and associated bits It's not obvious that there's an advantage to using fstatat in terms of performance. The race-avoidance properties of fstatat aren't terribly useful to us either. So best to avoid it until we figure out how to use it portably.

fix typo

import gettext since '_' is used
