I remember Kai did surgery in this place.  Did you identify a patch that caused
this regression?  My bet would be

2011-03-25  Kai Tietz  <ktietz@redhat.com>

        * collect2.c (write_c_file_stat): Handle backslash
        as right-hand directory separator.
        (resolve_lib_name): Use IS_DIR_SEPARATOR instead of
        checking just for slash.
        * coverage.c (coverage_init): Use IS_ABSOLUTE_PATH
        instead of checking for trailing slash.
        * gcc.c (record_temp_file): Use filename_cmp instead
        of strcmp.
        (do_spec_1): Likewise.
