# are needed for linking MPI (e.g. -lmpi or -lfmpi, if a special
# MPICC/MPICXX/MPIF77/MPIFC was not found).
#
# If you want to compile everything with MPI, you should use something
# like this for C:
#
# if test -z "$CC" && test -n "$MPICC"; then
# CC="$MPICC"
# fi
# AC_PROG_CC
# AX_MPI
# CC="$MPICC"
# LIBS="$MPILIBS $LIBS"
#
# and similar for C++ (change all instances of CC to CXX), Fortran 77
# (with F77 instead of CC) or Fortran (with FC instead of CC).
#
# NOTE: The above assumes that you will use $CC (or whatever) for linking
# as well as for compiling. (This is the default for automake and most
# Makefiles.)
#
# The user can force a particular library/compiler by setting the
# MPICC/MPICXX/MPIF77/MPIFC and/or MPILIBS environment variables.
# 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.
