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]
?
