// 4127 is constant conditional (assert)
// 4201 nonstandard extension used: nameless struct/union (happens a lot in Windows include headers)
// 4290 C++ exception specification ignored except to indicate a function is not __declspec(nothrow)
// 4390 empty control statement (triggered by nprintf and mprintf's inside of one-line if's, etc)
// 4410 illegal size for operand... ie... 	fxch st(1)
// 4511 copy constructor could not be generated (happens a lot in Windows include headers)
// 4512 assignment operator could not be generated (happens a lot in Windows include headers)
// 4514 unreferenced inline function removed, 
// 4611 _setjmp warning.  Since we use setjmp alot, and we don't really use constructors or destructors, this warning doesn't really apply to us.
// 4663 C++ language change (template specification)
// 4710 is inline function not expanded (who cares?)
// 4711 tells us an inline function was expanded (who cares?)
// 4725 is the pentium division bug warning, and I can't seem to get rid of it, even with this pragma.
//      JS: I figured out the disabling 4725 works, but not on the first function in the module.
//      So to disable this, I add in a stub function at the top of each module that does nothing.
// 4786 is identifier truncated to 255 characters (happens all the time in Microsoft #includes) -- Goober5000
// 4996 deprecated strcpy, strcat, sprintf, etc. (from MSVC 2005) - taylor
