Currently,

Run gdb (like this): gdb -fullname ~/myprog

works in CVS but:

Run gdb (like this): libtool gdb -fullname ~/myprog

doesn't as the GUD buffer is called gud-gdb and the default directory is not set
to that of the executable.

The patch above rectifies this (try it) by finding the start of gdb's
arguments and sets things up as without libtool. If I check with
list-processes, I can see that libtool has actually been invoked but I don't
know enough about libtool to know how the behaviour should differ. Presumably
you need a program with libraries that have been built by libtool(?).
