Hello,

This patch fixes some issues related to DOS file-system filenames and
paths. I am not sure, if I
hit all places, nevertheless I am sure I hit most.
This patch uses the libiberty functions & macros about
directory-separator checks, absolute-path checks,
and the filename-comparision functions.

Patch was tested for x86_64-w64-mingw32, i686-pc-cygwin, and
x86_64-pc-linux-gnu. Ok for apply?
