`-f' ignored? autom4te.cache issue?

[Alexandre Duret-Lutz]

This looks like a bug to me:

`autoconf -f' prints an error message while
`rm -Rf autom4te.cache; autoconf' doesn't.

~/tmp/clean % ls -la
total 8
drwxr-xr-x    2 adl      lrde         1024 Oct 10 17:38 ./
drwx------   13 adl      lrde         7168 Oct 10 17:38 ../
~/tmp/clean % cat > configure.ac

m4_include(bar)
~/tmp/clean % echo 'm4_include(foo)' > bar
~/tmp/clean % touch foo
~/tmp/clean % autoconf
~/tmp/clean % mkdir sub
~/tmp/clean % mv foo sub
~/tmp/clean % echo 'm4_include(sub/foo)' > bar
~/tmp/clean % autoconf
autom4te: no such file or directory: foo
~/tmp/clean % autoconf -f
autom4te: no such file or directory: foo
~/tmp/clean % rm -Rf autom4te.cache
~/tmp/clean % autoconf
~/tmp/clean %

This is Autoconf 2.54.
