[Scummvm-devel] PS2 backend - up & running (almost)

[Keith Scroggins]

Hello Max,

First off, yes, the m68k (and Coldfire) are targets still supported in 
GCC, actually, alot of work was done for the 4.3 series.

I'm going to foward this to the person who has been working on the Atari 
port specifically (had a previous problem compiling ScummVM in the past, 
and he sorted it out) and see if he thinks this should be passed on up the 
chain to be reported as a possible GCC bug.
