That matches my recollections on this compiler, thanks.

No idea about that.

Yeah, I know. We should fix Automake/Autoconf to cope better with this.
For the moment, if you don't compile any C, C++, or similar sources in
the directory where you compile the Fortran code, you should be able to
put something like this workaround in Makefile.am:
DEFS = -WF,-DHAVE_CONFIG_H
