Subject: [SDL] Windows MessageBox() strangeness fixes
Hello all,
I *think* this should fix the issues that people were seeing with
MessageBox() not working and therefore assert() on mingw/msvc. Forgive
me if i've screwed up making the diff file - I'm a total newb when it
comes to things like CVS and diff.
It modifies a few files as I saw that FlushMessageQueue() was in both
the windx5 and windib driver, so I moved this into wincommon. It was
also in the gapi driver, so I changed that too. The function is now
WIN_FlushMessageQueue() in src/video/wincommon/SDL_syswm.c
