# $(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).

At least a source file is in a subdirectory, but the 'subdir-objects'
automake option hasn't been enabled.  For now, the corresponding output
object file(s) will be placed in the top-level directory.  However,
this behaviour will change in future Automake versions: they will
unconditionally cause object files to be placed in the same subdirectory
of the corresponding sources.
You are advised to start using 'subdir-objects' option throughout your
project, to avoid future incompatibilities.

      # source tree.  This was an obstacle to the support of
      # non-distributed .info files, and non-distributed .texi
      # files.
      #
      # * Non-distributed .texi files is important in some packages
      #   where .texi files are built at make time, probably using
      #   other binaries built in the package itself, maybe using
      #   tools or information found on the build host.  Because
      #   these files are not distributed they are always rebuilt
      #   at make time; they should therefore not lie in the source
      #   directory.  One plan was to support this using
      #   nodist_info_TEXINFOS or something similar.  (Doing this
      #   requires some sanity checks.  For instance Automake should
      #   not allow:
      #      dist_info_TEXINFOS = foo.texi
      #      nodist_foo_TEXINFOS = included.texi
      #   because a distributed file should never depend on a
      #   non-distributed file.)
      #
      # * If .texi files are not distributed, then .info files should
      #   not be distributed either.  There are also cases where one
      #   wants to distribute .texi files, but does not want to
      #   distribute the .info files.  For instance the Texinfo package
      #   distributes the tool used to build these files; it would
      #   be a waste of space to distribute them.  It's not clear
      #   which syntax we should use to indicate that .info files should
      #   not be distributed.  Akim Demaille suggested that eventually
      #   we switch to a new syntax:
      #   |  Maybe we should take some inspiration from what's already
      #   |  done in the rest of Automake.  Maybe there is too much
      #   |  syntactic sugar here, and you want
      #   |     nodist_INFO = bar.info
      #   |     dist_bar_info_SOURCES = bar.texi
      #   |     bar_texi_DEPENDENCIES = foo.texi
      #   |  with a bit of magic to have bar.info represent the whole
      #   |  bar*info set.  That's a lot more verbose that the current
      #   |  situation, but it is # not new, hence the user has less
      #   |  to learn.
      #	  |
      #   |  But there is still too much room for meaningless specs:
      #   |     nodist_INFO = bar.info
      #   |     dist_bar_info_SOURCES = bar.texi
      #   |     dist_PS = bar.ps something-written-by-hand.ps
      #   |     nodist_bar_ps_SOURCES = bar.texi
      #   |     bar_texi_DEPENDENCIES = foo.texi
      #   |  here bar.texi is dist_ in line 2, and nodist_ in 4.
      #
      # Back to the point, it should be clear that in order to support
      # non-distributed .info files, we need to build them in the
      # build tree, not in the source tree (non-distributed .texi
      # files are less of a problem, because we do not output build
      # rules for them).  In Automake 1.7 .info build rules have been
      # largely cleaned up so that .info files get always build in the
      # build tree, even when distributed.  The idea was that
      #   (1) if during a VPATH build the .info file was found to be
      #       absent or out-of-date (in the source tree or in the
      #       build tree), Make would rebuild it in the build tree.
      #       If an up-to-date source-tree of the .info file existed,
      #       make would not rebuild it in the build tree.
      #   (2) having two copies of .info files, one in the source tree
      #       and one (newer) in the build tree is not a problem
      #       because 'make dist' always pick files in the build tree
      #       first.
      # However it turned out the be a bad idea for several reasons:
      #   * Tru64, OpenBSD, and FreeBSD (not NetBSD) Make do not behave
      #     like GNU Make on point (1) above.  These implementations
      #     of Make would always rebuild .info files in the build
      #     tree, even if such files were up to date in the source
      #     tree.  Consequently, it was impossible to perform a VPATH
      #     build of a package containing Texinfo files using these
      #     Make implementations.
      #     (Refer to the Autoconf Manual, section "Limitation of
      #     Make", paragraph "VPATH", item "target lookup", for
      #     an account of the differences between these
      #     implementations.)
      #   * The GNU Coding Standards require these files to be built
      #     in the source-tree (when they are distributed, that is).
      #   * Keeping a fresher copy of distributed files in the
      #     build tree can be annoying during development because
      #     - if the files is kept under CVS, you really want it
      #       to be updated in the source tree
      #     - it is confusing that 'make distclean' does not erase
      #       all files in the build tree.
      #
      # Consequently, starting with Automake 1.8, .info files are
      # built in the source tree again.  Because we still plan to
      # support non-distributed .info files at some point, we
      # have a single variable ($INSRC) that controls whether
      # the current .info file must be built in the source tree
      # or in the build tree.  Actually this variable is switched
      # off in two cases:
      #  (1) For '.info' files that appear to be cleaned; this is for
      #      backward compatibility with package such as Texinfo,
      #      which do things like
      #        info_TEXINFOS = texinfo.txi info-stnd.texi info.texi
      #        DISTCLEANFILES = texinfo texinfo-* info*.info*
      #        # Do not create info files for distribution.
      #        dist-info:
      #      in order not to distribute .info files.
      #  (2) When the undocumented option 'info-in-builddir' is given.
      #      This is done to allow the developers of GCC, GDB, GNU
      #      binutils and the GNU bfd library to force the '.info' files
      #      to be generated in the builddir rather than the srcdir, as
      #      was once done when the (now removed) 'cygnus' option was
      #      given.  See automake bug#11034 for more discussion.

    It appears this file (or files included by it) are triggering

    Future automake versions will no longer place in the builddir
    (rather than in the srcdir) the generated '.info' files that
    appear to be cleaned, by e.g. being listed in CLEANFILES or
    DISTCLEANFILES.
    If you want your '.info' files to be placed in the builddir
    rather than in the srcdir, you have to use the shiny new
    'info-in-builddir' automake option.

# * warning and (normal) error messages, for stable stderr output
#   order and content (avoiding duplicates, for example),
# * races when installing aux files (and respective messages),
# * races when collecting aux files for distribution.

# The latter requires that the makefile that deals with the aux dir
# files be handled last, done by the master thread.
