If you used gcc to compile the X11 release in time past, you
noticed that some button-boxes (notably the ones in xmh)
didn't hi-lite properly when selected.

Well, gcc 1.25 no longer causes that problem to occur.

I compiled the whole X11 distribution (modified with out
speed-ups plus some small code changes to make gcc happy)
with the options 
    -finline-functions -fcombine-regs -fomit-frame-pointer -O
(plus, of course, -traditional), and the resulting code
works 100% and is quite fast.

Two files dumped core with an IOT trap during the rebuild, and
those have been reported in the gcc bug list; compiling those
files with sun cc -O works fine.

Just thought you'd all like to know....
