acx_mpi and ac_lang_push

[Jim Edwards]

Hi,

I have a configure script that uses acx_mpi from the macro archive.   It
then wants to test some features of the MPI implementation such are whether
mpi-io is supported, and I am trying to improve these tests to add them to
the archive.   So ACX_MPI sets MPICC or MPIFC or MPIF77  and MPILIBS , but
then my subsequent tests want to use AC_LANG_CASE which falls back to CC or
FC or F77 - is there a way to make AC_LANG_* recognize the MPI variants of
the
compilers?   Other suggestions on how I might do this?

Thanks,
Jim
