Um, does this Chnagelog entry ring a bell?

* configure.in:
added a program that tests for -Werror option and similar; bug out of
configure if the test program doesn't compile
We discussed this a while ago to provide a better error message
when configure is run with -Werror in the CFLAGS. I don't
remember exactly, but I asked for a valid program with several
warnings on the list and included it in confiure.in. That has
nothing to do with autoconf.
Bye
