[issue777] msvc does not have ssize_t

[Shun-ichi Goto]

New submission from Shun-ichi Goto <shunichi.goto at gmail.com>:

mpatch.c uses the type ssize_t since r5444, but MSVC 7 (used for python 2.4) 
does not have it. So build fails.
MSVC 8 (Visual Studio 2005) also not.

# building with MinGW is ok.
