Comment (by gdt):

 I have run into this with other projects.  Basically, configure.ac ( :-) )
 has to check each compiler option to see if it's really ok before adding
 it to CFLAGS.   And, because one often wants -Werror, you have to add in
 -Werror first so that -Wfoo will fail compilation instead of giving a
 warning and being judged acceptable.   And, if you don't want -Werror, I
 think one has to capture stderr, or use -Werror on the test calls.
