Hi folks
I have been trying (without success) to suppress a flood of warnings I now get

This started appearing when we switched to autoconf-2.68 and libtool-2.4. I've
tried adding AC_LANG directives, but I can't find a consistent way to eliminate
these outputs. I've looked at your mailing list archives, and the claim was
that libtool-2.4 would solve it - but that doesn't work for us.
Use of libtool 2.4 will solve libtool's violation of the rule, but not
the EVENT_CHECK_VISIBILITY macro.
Any suggestions? I can provide copies of the configure.in and other m4's, if
that would help.
Most likely, you are missing a quoted call to AC_LANG_SOURCE in the
definition of EVENT_CHECK_VISIBILITY - what does the .m4 file look like
that provides that macro?
