The Dual Core and Quad Core options specify the number of processes spawned during compilation, so they can really speed up the compiling process.
Question: Does using different compile options result in the exact same mame.exe? In other words they only affect how efficiently the same mame.exe is compiled?
Or, do the different options produce different mame.exe's optimized somehow for different processors and instruction sets?
Also, is there ever a reason NOT to use the Disable Warnings as Error option?
<edit> Well, after lots of compiling, it appears that the different compile options affect not only the compiling process, but also the end result. So if I compile a quad core version, the compiler makes a quad core mame, and uses four cores to do it. That's pretty clever but I wonder if they could be separated, because if I compile a single core version on my quad core machine, my four cores are not fully utilized.
