Subject: [PATCH] - Updated Zlib definitions to version 1.2.3. The only
 difference is that the function calling convention has changed on Win32
 (previously, the zlib DLL used WINAPI). YOU NOW NEED AN OFFICIAL "zlib1.dll"
 version 1.2.x instead of your old "zlib.dll" (get it from
 http://www.zlib.net/). If you still want to use a DLL with the old calling
 convention, uncomment line 101 and recompile (such a DLL can be found at
 http://www.winimage.com/zLibDll/). - Removed QuakeForge copyright since the
 last bit of QF code was removed months ago by LordHavoc - Changed the way we
 test the presence of the O_NONBLOCK flag
