Re: AC_PROG_F77 thinks my compiler is g77 (its not!)

Thanks for tracking this down.  In fact the problem is that I'm not
sure what should be done out of the PROLOGUE in the case of
AC_LANG_PROGRAM(Fortran 77).  Maybe you can answer me.

For C for instance, we have:

# AC_LANG_PROGRAM(C)([PROLOGUE], [BODY])
# --------------------------------------
m4_define([AC_LANG_PROGRAM(C)],
[$1
int
main ()
{
dnl Do *not* indent the following line: there may be CPP directives.
dnl Don't move the `;' right after for the same reason.
$2
  ;
  return 0;
}])


but for Fortran 77, $1 was ignored :(

# AC_LANG_PROGRAM(Fortran 77)([PROLOGUE], [BODY])
# -----------------------------------------------
# Yes, we discard the PROLOGUE.
m4_define([AC_LANG_PROGRAM(Fortran 77)],
[      program main
$2
      end])


So, what should it be?

[      program main
$1
$2
      end]

or

[$1
      program main
$2
      end]

?
