Yes, there can be all kinds of hidden dependencies and/or bootstrap
issues with linking Fortran codes with the C compilers. We've
typically used the table in the Automake docs to determine which
linker is used to understand this stuff (well, it *used* to be a
table, but I think AM now supports too many languages/compilers to
make it a simple table -- in the AM 1.10 docs, it's 8.13.3.1: "How the
Linker is Chosen").

Subject: Fwd: mpicc does not link against Fortran libraries?
Is it considered a feature that mpicc does not automatically link
against the Fortran libraries?
When I have a C main that uses a few Fortran functions down in the
guts I like to link with the
C linker, but mpicc does not appear to automatically link against
the Fortran libraries (mpif90 does
link against the C MPI libraries :-)).
Is this something that could get changed?
Thanks
Barry
