Hello all,

A few questions...

What are your suggestions about the best way to debug a graphics
program?  gdb runs my program fine, but when a breakpoint is hit with
the screen in a graphics mode I can't read the text printed by gdb.

Actually, if I could get what gdb tries to print to be visible, I could
do my debugging with printfs (yuk, but it would help).  All I see are
white squares on a black background.  It's as if the bios font is
screwed up or some attribute bit is set wrong, but I can't figure out
where.

Who's maintaining the bcc2grx stuff?  It's a very helpful package, but
mail to Hartmut Schirmer (who wrote the readme for that package) at
PHC27 AT rz DOT uni-kiel DOT dbp DOT de bounces hard.

Thanks in advance!
