[Spice-devel] [PATCH win-agent 4/9] mingw: don't use *_s msvcrt variants

[Marc-André Lureau]

Apparently, it comes with a recent version of C library (msvcrt90?),
but I don't know if we can/should ship also a MS dll. Probably it used
to work with an inlined version with VS headers.

The build can be tweaked to use the -non-_s variant with -DOLDMSVCRT
CFLAGS.
