	Could anyone tell me what bugs there are in the DRI C compiler?
I am working on some GEM programs, and I keep getting bus errors (the
ole' double mushrooms...).  I couldn't think of anything I did wrong,
so I atarted wondering about a bug in the compiler (Yeah...if the program
doesn't work blame it on the compiler...I know.).  In any case, the bus
error comes in on a link instruction, which looks awfully close to a local
variable init code.  Is there any chance that the DRI C compiler has a
frame problem somewhere?  I would appreciate any info and possible fixes.

	Also, how have people approached window text scrolling?  V_gtext
is far too slow for a complete offset text redraw.  I would like to do
a bit scroll, but the GEM manual was very hazy on how to do this, and I
am not sure if desk accessories on top of a window would screw up the
bits when scrolled.  I actually would like a scroll rectangle call like
on the Macintosh, that gives redraw messages for the scrolled area under
the desk accessory.  Any help here would also be great...

						Thanks,
