* make-relative-prefix.c (make_relative_prefix_1): Avoid warning
about using preprocessor directives inside of macro arguments.

* make-relative-prefix.c (make_relative_prefix_1): Avoid
stack overflow if PATH contains just a single entry and
HOST_EXECUTABLE_SUFFIX needs to be used.
PR driver/48306
* make-relative-prefix.c: Include sys/stat.h.
(make_relative_prefix_1): If access succeeds, check also stat
if nstore is a regular file.
