Re: duplicated source file names

[Andrew Cagney <ac131313@redhat.com>]

"It should work".

With out any other evidence, I'd assume this is fixed in a more recent 
set of developer tools (debugger, binutils, compiler, ...).  Perhaps 
look in GDB's bug database - http://www.gnu.org/software/gdb/bugs/.

BTW, the current reason for GDB having uniquely named files is for 
consistency and to avoid the build problems with:
	cc -c a/foo.c
	cc -c b/foo.c

enjoy,
Andrew
