 Actually, *other* tests in the same configure script will give wrong
results if "-Werror" passed, so ideally it should be easy to give
"-Werror" for that single test only. So maybe filtering by default but
storing information whether "-Werror" was part of original CFLAGS
(CXXFLAGS, CPPFLAGS?) to documented variable or other part of official
API for configure.ac author to reinstate "-Werror" at will.

 This leaves me just wrapping my head around what will happen to other
variables with values based on contents of CFLAGS while it was
filtered, and does it even matter.
