That's a VERY old version of GDB!  Not that I think it must be the
reason for the original problem, but you can upgrade to GDB 6.7 on the
MinGW site.

Well, how about if you describe your build environment: what kind of
shell and Make programs do you use, which compiler, what versions of
ported rm and mv, etc.  Could it be that your are hitting one of the
combinations mentioned in nt/INSTALL that are known to fail?

Also, did you ever build the CVS version on this machine with these
development tools, and if so, when was the last time you succeeded?
