One more related thing:

libiberty/make-relative-prefix.c uses case sensitive comparisson for 
filenames. In thee case we should (fMSDOS, Windows) use strcasecmp()
instead of strcmp(). strcasecmp() is already present in libiberty, so it 
should not be a problem. Perhaps it could be done by some macro
with the defaulting to strcmp().
