I refer you to:

Daniel's concerns are raised in:

http://sources.redhat.com/ml/gdb-patches/2002-09/msg00322.html

and I provided answers in:

http://sources.redhat.com/ml/gdb-patches/2002-09/msg00324.html

BTW I should point out that this patch is relative to another patch
I made to introduce openp_1() which implements openp() but allows
it to be immune to occurrences of DIRNAME_SEPARATOR which
can appear in the filenames embedded in the debugging information.

When this occurs, substitution into $cdir causes surprising
results!

This is a particular risk in Win32 environments because : can
occur in the context of filenames.

See

http://sources.redhat.com/ml/gdb-patches/2002-09/msg00317.html

for details.
