# $(CPPFLAGS)' as additional flags to the Fortran 77 compiler, since
# this is how GNU Make does it; see the `GNU Make Manual, Edition 0.51
# for `make' Version 3.76 Beta' (specifically, from info file
# `(make)Catalogue of Rules').
#
# A better approach would be to write an Autoconf test
# (i.e. AC_PROG_FPP) for a Fortran 77 preprocessor, because not all
# Fortran 77 compilers know how to do preprocessing. The Autoconf
# macro AC_PROG_FPP should test the Fortran 77 compiler first for
# preprocessing capabilities, and then fall back on cpp (if cpp were
# available).
