Right.

No, sorry; but the Autoconf Macro Archive has a similar macro IIRC.
Also note that AC_FC_PP_DEFINE is not a full solution to the
problem.  Automake still uses $(DEFS) instead of switching to a new
variable like $(FCDEFS) or so, which Autoconf still needs to export.

Cf. http://lists.gnu.org/archive/html/autoconf/2011-05/msg00017.html

Hope that helps.
