Close - first is the current dir, second is the path passed.

With cwd=E:/Tmp, containing foo.c, I tried

gcc -S foo.c
gcc -S ../tmp/foo.c
gcc -S /tmp/foo.c
gcc -S e:/tmp/foo.c
gcc -S e:\tmp/foo.c
gcc -S e:\tmp\foo.c

In each case, the first entry was "e:/Tmp/", and the second the path
exactly as passed (with backslashes preserved).
objdump -g shows as filenames for the above:

E:/Tmp/foo.c
E:/Tmp/../tmp/foo.c
/tmp/foo.c
e:/tmp/foo.c
e:\tmp/foo.c
e:\tmp\foo.c

So I cannot reproduce the bug (either with my local cvs binutils, or Mark's
2.11 package)

In any case, using the basename would be wrong, as that would break debug
info for files compiled in a subdir (gcc -c foo/bar.c would produce a
reference to $CWD/bar.c instead of $CWD/foo/bar.c).
