Help... GDB no longer works after updating...

[Kris Erickson <kris at mha dot ca>]

I had been happily (very happily) using GDB for debugging until this morning,
when I decided to update my cygwin files (have to keep current).  Now GDB won't
run anything.  I did a search on google and the cygwin lists on 
"unknown target exception", but everything I came up with seems fairly out of
date...

Here is a simple test file I created, the error that it generates and executing
the show command.

I have tried re-installing gdb, cygwin, w32api, gcc but nothing has changed.  I
tried going back a version in w32api and cygwin but that didn't help either...
I really don't want to have to blow away my whole cygwin distribution because it
took months to get X and all the nice utilities installed and compiled...

Thank any of you for your help in advance,

Kris
