Ah, finally a good soul with an honest-to-goodness data point!
Who knew there were actually 486s still around. ;-)  Seems like 
this lends credence to Chris' arguments (did he need some? :-) )  

Chuck, if you're seeing some problem and want to try to get it 
resolved, you need to push into a different area to track it 
down, assuming it's something you want to pursue.

Dead thread now?  I hope so.  I'm out. :-)

Larry

I tried gdb (the version you cited) with the windowed interface on a 486 
running NT 4.0, and it appeared to work fine on a simple "hello, world" 
test program.  Do you have steps to reproduce your problem?

Regarding the "i686" configuration, I believe Randall Schulz cited the 
appropriate part of the gcc manual, i.e., unless specifically directed to 
do so, the compiler will output i386 instructions.  I don't have a 486 
datasheet handy, but I'm reasonably certain that the 486 had an illegal 
instruction trap (the 386 did), so if a Pentium-only instruction was 
encountered, you'd encounter an exception.  Are you getting illegal 
instruction exceptions?

As a data point, I've run Cygwin on a 486 system for some years and never 
had a problem related to the CPU configuration.
