Please ignore that message.  I was reading both AC_CHECK_MEMBER and
config.log wrongly, more specifically I overlooked that there is a
second compile test to make up for a failure in the first one.

Sorry about the noise.

To keep myself from missing this again, I applied this patch to the
Autoconf test suite.

Cheers,
Ralf

        * tests/semantics.at (AC_CHECK_MEMBERS): Also test with a struct
        member.
