Hello! Test 13 (m4_warn) fails in the CVS version of Autoconf. It turns out that autoconf doesn't report any warnings at all until autom4te.cache is removed: $ cat >configure.ac <<EOF > m4_warn([foo], [foo]) > m4_warn([bar], [bar]) > m4_warn([syntax], [syntax]) > EOF $ rm -rf autom4te.cache $ autoconf configure.ac:3: warning: syntax $ autoconf $ rm -rf autom4te.cache $ autoconf configure.ac:3: warning: syntax $ Removing autom4te.cache between autoconf invocations fixes the test, but I believe that the actual problem is in autoconf, not in the test. -- Regards, Pavel Roskin
