    build-sys: avoid icc warnings "ignoring unknown option" · e85e8720
    Ruediger Meier authored
    Our macro UL_WARN_ADD could not discover these ones:
    icc: command line warning #10006: ignoring unknown option '-Wmissing-parameter-type'
    icc: command line warning #10006: ignoring unknown option '-Wredundant-decls'
    icc: command line warning #10006: ignoring unknown option '-Wunused-result'
    icc: command line warning #10006: ignoring unknown option '-Wnested-externs'
    
    We need to use AC_LANG_WERROR.
