[Qemu-devel] [PULL 19/35] build-sys: move windows defines in osdep.h header

[Paolo Bonzini]

From: Marc-André Lureau <address@hidden>

This removes some clutter in compilation logging, and allows some
easier tweaking per compilation unit/CFLAGS overriding.

Note that we can't move those define in os-win32.h, since they must be
set before the first system headers are included.
