What target did you build for? Your configure options only list --build 
and --host.

Also, what target are you trying to debug under? The problem you 
describe is typically a bug in the target back-end. It would not 
surprise me to find out that something changed in gdb-land that broke 
insight. This happens more often than I would like, but since I only use 
insight natively, unless I can reproduce on a simulator, my bug-solving 
is limited to what I can divine by reading the code.

That doesn't surprise me. Our tcl/tk are greatly out of date, and I do 
not have general access to a windows machine. I've never tried building 
a cross from linux, though...

Configure will look for t{cl,k}Config.sh in the install directory and 
several other places. Wherever it finds those files, the location will 
be hard-coded into configure's cache (if what I am deducing from my 
vague recollection of how this all works is accurate). Your description 
makes sense. That is simply a quirk of how configure works.

Next time, try erasing the gdb directory and forcing a reconfigure.
