I just ran CVS autoconf on my Tru64 5.1A unix workstation and noticed
a testsuite failure during `GNU Fortran 77' using vendor fortran
compilers (f77, f90, f95).

The test fails for 2 reasons:

- There is an unquoted $G77 variable.
  Using non Gnu fortran 77 compilers make this variable empty, and
  then generate a test with a missing argument. At lest Tru64 /bin/sh
  choke on that.

- Tru64 fortran compilers f{77,90,95} generate `a.out' file if called
  with unknown arguments. This is the case in `_AC_PROG_FC', while
  getting information from the compiler :

address@hidden [tmp/fortran]> ls -l
total 0
address@hidden [tmp/fortran]> f77 --version
f77: Severe: Failed while trying to link.
address@hidden [tmp/fortran]> ls -l
total 25
-rw-r--r--   1 njoly    sis        25200 Sep 29 17:16 a.out
address@hidden [tmp/fortran]> 

With the following patch, all tests are successful.

Hope this helps,
