This is fixed in the CVS version of Autoconf. The testsuite won't fail
anymore because of a broken compiler. Unfortunately, `fc' will still be
picked as a Fortran compiler.

A comment in aclang.m4 is quite clear:

# `fort77' and `fc' are wrappers around `f2c', `fort77' being better.

I agree that `fc' is very inconvenient to use. It's a builtin command in
bash and possibly other shells. Unfortunately, I don't know how widespread
the name `fc' was for legitimate Fortran compilers.

I won't object against excluding `fc' from the default list of known
fortran compilers.
