Did you try to use
dir /p/..
because it might be that gdb
does try 
/p/../a/x/foo.c
normally this should be 
expanded back into /a/x/foo.c
but we could probably easily get GDB to handle
it the other way around so that it gets translated into
/p/x/foo.c.

This would of course require some documentation
about this new feature, but as dir /p/..
is probably quite useless for now,
it could be adapted for this purpose,
without the need of a new gdb command.
