That "b.out" is due to a bug in Autoconf; it incorrectly deduced the
name of the executable. What is the name of the executable that your
GNU Fortran 95 compiler outputs? That is, if you execute this shell
script:
cat >conftest.f <<'EOF'
program main
end
EOF
g95 conftest.f
what file does your g95 compiler create?
I installed the following patch to fix the other bugs noted in your
report. Thanks again.

Fix test suite failures reported by Pierre in
<http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
* lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
the compiler created a file "b.out" when it didn't create anything
at all.
* lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
Discard stderr too, when invoking the test script.
