Oh, yeah that's wrong. On win64 ssize_t cannot be a long, it needs to be a
proper 64bit value, size_t but signed.

All 64 bit systems known to man *except* win64, use 64bit longs. So yeah, this
is a win64 specific problem.

Where is ssize_t typedefed to a long? Shouldn't it be defined to use __int64
in lib/config-win32.h on line 379 ?
