The -mcpu=G4 flag is for use in conjunction with -fast, there is a 
second flag -mtune=G4 that is also for use with -fast, they actually 
unset a flag that is set by default.
-fast sets:

-falign-loops-max-skip=15

-falign-jumps=16

-fast is probably only for G4 G5s since it doesn't list a G3 flag. I 
have found one problem, some times opening the file select window 
causes blender to crash, but not every time, I'm trying to figure out 
what the difference is between it working and not. As for binary's that 
are compiled on a G4 with -fast set working on a G3........??? that is 
a good question. I could e-mail the binary (package) if you're using a 
G3 (9.5meg it will compress some though). I just compiled the 
blender230 CVS, and the file select windows work every time now. f-11 
does have some strange behavior though, the render window goes away but 
so does the main blender window.
