commit 9077bf12d8f0b0b6c6cdf94a1ef7837b9a2f5b6c
Author: Jim Meyering <address@hidden>
Date:   Wed Dec 10 14:45:35 2008 +0100

    AC_HEADER_ASSERT: don't say assertions are disabled when they're not
    
    * lib/autoconf/headers.m4 (AC_HEADER_ASSERT): Do not make configure
    report "checking whether to enable assertions... no", when they are
    in fact enabled.  This is solely a bug in the output of configure.
    In spite of saying "no", NDEBUG was not defined in that case.
    Also, as noted by Eric Blake, leave assertions enabled upon
    --enable-assert=INVALID.
