Remove some complier warnings from msvc in compat/mingw.c for value truncation from 64 bit to 32 bit integers. Compiling compat/mingw.c under a 64 bit version of msvc produces warnings. An "int" is 32 bit, and ssize_t or size_t should be 64 bit long. Prepare compat/vcbuild/include/unistd.h to have a 64 bit type _ssize_t, when _WIN64 is defined and 32 bit otherwise. Further down in this include file, as before, ssize_t is defined as _ssize_t, if needed. Use size_t instead of int for all variables that hold the result of strlen() or wcslen() (which cannot be negative). Use ssize_t to hold the return value of read().
