How can GDB figure that out?  We don't tell it enough about the
program being debugged for that.

But if I'm wrong, and GDB _can_ figure it out on its own, then it
should use the right style of file names automagically, and the _ANY
set of macros is again not needed.

If GDB cannot figure this out, the user should tell it, since the user
always knows.

How about

 (gdb) set filename-style (dos|unix)

?

No more cumbersome than any other similar option, like "set
demangle-style", for example.
