I'm not sure yet.  My doubt stems from the fact that directories are
also recorded in the debug info, at least with some formats (stabs,
DWARF2).  One place in GDB where we use this is in file-name
completion, for example when you type "break /foo TAB" and want GDB
to complete this to "break /foobar/foo.c" (assuming that there's only
one file foo.c in that directory that was compiled into the program).

Will this break if symlinks are followed in the directory part, but
not in the file-name part?
