win32: Define the ssize_t type using SSIZE_T if supported

Browse Source 
Some win32 compilers define the SSIZE_T type, with the same
meaning and intent as ssize_t. If available, make ssize_t a
synonym of SSIZE_T.

At present, the Digital-Mars compiler is known not to define
SSIZE_T, so we provide an SSIZE_T macro to use in the typedef.
