    Make sure to use SDL_CFLAGS everywhere we include SDL headers

Seems to be a bug in your MinGW installation, the function should be
implemented in libmingwex.a. I'm using mingw runtime 3.15.2 and
everything links just fine.

Looks like my older MinGW doesn't implement it - will upgrade. Thanks.

After the upgrade to 3.15.2 it does indeed link fine. But it seems the commit
broke output to console:

(no output here)

I've already reported this earlier on the mailing list. Technically
it's SDL "feature".

http://www.emclient.com/temp/libSDLmain.zip - here you can get
precompiled library with disabled console redirection.
