warning from AC_LANG_PROGRAM(Fortran 77)

[John W. Eaton]

I'm using Autoconf 2.59:

devzero:450> autoconf --version
autoconf (GNU Autoconf) 2.59

Given the following input file

AC_INIT
AC_PREREQ(2.50)
AC_LANG_PUSH(Fortran 77)
AC_TRY_LINK([],[],[])
AC_LANG_POP(Fortran 77)

Autoconf emits the following warning:

devzero:449> autoconf foo.in > foo.out
foo.in:4: warning: AC_LANG_PROGRAM(Fortran): ignoring PROLOGUE: []
autoconf/lang.m4:224: AC_LANG_SOURCE is expanded from...
autoconf/lang.m4:234: AC_LANG_PROGRAM is expanded from...
autoconf/general.m4:2215: AC_LINK_IFELSE is expanded from...
autoconf/general.m4:2223: AC_TRY_LINK is expanded from...
foo.in:4: the top level

The INCLUDES argument ($1) of AC_TRY_LINK is empty, so I don't think I
should see a warning about ignoring that as there is nothing to
ignore.  Is there any way to avoid this warning?

Thanks,
