Hi all again!
After the discussion on the mailing list and the subsequent
modifications I did to the AX_PROG_{CC,FC,F77,CXX}_MPI macros, I want to
suggest that these new macros should be included into the autoconf macro
archive.
You can pull the new macros and the modifications to the documentation
of the older macro AX_MPI from here:
https://github.com/olenz/autoconf-archive
For reference, I have attached the new macros as well as the modified
ax_mpi.m4 to this mailing.

# SYNOPSIS
#
# AX_MPI([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
#
# DESCRIPTION
#
# This macro tries to find out how to compile programs that use MPI
# (Message Passing Interface), a standard API for parallel process
# communication (see http://www-unix.mcs.anl.gov/mpi/)
#
# On success, it sets the MPICC, MPICXX, MPIF77, or MPIFC output variable
# to the name of the MPI compiler, depending upon the current language.
# (This may just be $CC/$CXX/$F77/$FC, but is more often something like
# mpicc/mpiCC/mpif77/mpif90.) It also sets MPILIBS to any libraries that
# are needed for linking MPI (e.g. -lmpi or -lfmpi, if a special
# MPICC/MPICXX/MPIF77/MPIFC was not found).
#
# Note that this macro should be used only if you just have a few
# source files that need to be compiled using MPI. In particular,
# you should neither overwrite CC/CXX/F77/FC with the values of
# MPICC/MPICXX/MPIF77/MPIFC, nor assume that you can use the same
# flags etc. as the standard compilers.
# If you want to compile a whole program using the MPI compiler
# commands, use one of the macros AX_PROG_{CC,CXX,FC}_MPI.
#
# ACTION-IF-FOUND is a list of shell commands to run if an MPI library is
# found, and ACTION-IF-NOT-FOUND is a list of commands to run if it is not
# found. If ACTION-IF-FOUND is not specified, the default action will
# define HAVE_MPI.

# SYNOPSIS
#
# AX_PROG_FC_MPI([MPI-WANTED-TEST[, ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]]])
#
# DESCRIPTION
#
# This macro tries to find out how to compile Fortran77 programs
# that use MPI (Message Passing Interface), a standard API for
# parallel process communication (see
# http://www-unix.mcs.anl.gov/mpi/). The macro has to be used
# instead of the standard macro AC_PROG_FC and will replace the
# standard variable FC with the found compiler.
#
# MPI-WANTED-TEST is used to test whether MPI is actually wanted by
# the user. If MPI-WANTED_TEST is omitted or if it succeeds, the
# macro will try to find out how to use MPI, if it fails, the macro
# will call AC_PROG_CC to find a standard C compiler instead.
#
# When MPI is found, ACTION-IF-FOUND will be executed, if MPI is not
# found (or MPI-WANTED-TEST fails) ACTION-IF-NOT-FOUND is
# executed. If ACTION-IF-FOUND is not set, the macro will define
# HAVE_MPI.
#
# EXAMPLE
#
# # If --with-mpi=auto is used, try to find MPI, but use standard FC
# compiler if it is not found.
# # If --with-mpi=yes is used, try to find MPI and fail if it isn't
# # found.
# # If --with-mpi=no is used, use a standard FC compiler instead.
# AC_ARG_WITH(mpi, [AS_HELP_STRING([--with-mpi],
# [compile with MPI (parallelization) support. If none is found,
# MPI is not used. Default: auto])
# ],,[with_mpi=auto])
#
# AX_PROG_FC_MPI([test x"$with_mpi" != xno],[use_mpi=yes],[
# use_mpi=no
# if test x"$with_mpi" = xyes; then
# AC_MSG_FAILURE([MPI compiler requested, but couldn't use MPI.])
# else
# AC_MSG_WARN([No MPI compiler found, won't use MPI.])
