There is no problem with backslashes in path names on Unix-like
systems.  Backslashes don't have a special meaning; they're just like
normal letters.  That's exactly why a native debugger on a Unix-like
system should not try to be DOS compatible at all.  And if you ask me,
the same is true for a cross-debugger for a Unix-like target running
on a Unix-like host.
