What source to change for compiling SDLMame without warning screens?

[Blanka]

I've been searching the internet a couple of hours to find out how to compile SDLMame without warning screens.
I read things like "everyone with only half a brain can do this", or "It only needs removal of 1 line of source code", but nowhere I see what to change.
So which line of code needs to be removed, and from which file?

I'm successful with the basic compiling now.
I saw this topic. If I use the hi136.diff from this page:
http://forum.arcadecontrols.com/index.php?topic=64298.0
Compiling results in an error. Guess I need a dif file for SDL mame. Anyone know where to get the SDLMame versions?

After some puzzling I found this works:

Open Terminal
Type "cd "
Drag the folder the SDL source is in on the Terminal window
Type "Make TARGETOS=macosx"
Wait....
Copy mame to your MAME folder.
