Autoconf testsuite: fortran-related failures on debian unstable

[Stefano Lattarini]

Hello everybody.

When I run the testsuite of the latest version of autoconf (from Git
master branch) on my debian unstable system, the following three
tests fail:

268: GNU Fortran 77 (fortran.at:31)
270: AC_F77_MAIN  (acfortran.at:13)
271: AC_F77_WRAPPERS (acfortran.at:14)

I have two fortran compilers in my PATH, both of them installed from 
debian packages.

One is `gfortran':

  $ which gfortran
  /usr/bin/gfortran
  $ dpkg -l gfortran
  ...
  ii  gfortran  4:4.3.3-9  The GNU Fortran 95 compiler
  $ gfortran --version
  GNU Fortran (Debian 4.3.4-2) 4.3.4
  Copyright (C) 2008 Free Software Foundation, Inc.
  ...

The other one (which is also the default Fortran 77 compiler) is
`fort77' (wrapper arounf f2c+gcc):
  
  $ update-alternatives --display f77
  f77 - auto mode
   link currently points to /usr/bin/fort77
  /usr/bin/fort77 - priority 10
   slave f77.1.gz: /usr/share/man/man1/fort77.1.gz
  Current `best' version is /usr/bin/fort77.
  $ which f77
  /usr/bin/f77
  $ readlink -f /usr/bin/f77
  /usr/bin/fort77
  $ dpkg -l fort77
  ...
  ii  fort77  1.15-8  Invoke f2c like a real compiler
  $ f77 -v
  /usr/bin/f77: fort77 Version 1.15
  /usr/bin/f77: No input files specified
  $ head /usr/bin/f77
  #! /usr/bin/perl
  # fort77 (compiler driver) script for f2c
  # For use with gcc
  # This code is in the public domain; use at your own risk.
  ...
  $version = "1.15";
  $nnflag = '-Nn802';
  ...

I have attached the `testsuite.log' file produced by the testsuite 
script.

Let me know if you need more information.

Regards,
     Stefano
