Authentication-results: sourceware.org; auth=none

GFortran's scanner appears to go into an infinite loop if you try topass a directory to 'include'. This patch will check for a directoryusing stat() after fopen() has verified its existence.

I'm assuming stat() will be OK to call here since add_path_to_list usesit. I've only been able to check it on a Linux system so far.

Botstrapped and tested for regressions on x86_64-pc-linux-gnu. There isa test case for the bug included.

My office is about to close for the Christmas holiday, so I apologise ifI don't respond to questions promptly.

	PR fortran/69043
        * scanner.c (load_file): Abort and show	an error if stat() shows
        the path is a directory.
