Subject: [PATCH 1/2] build: accommodate gnulib's new warnings with
--enable-gcc-warnings
* configure.ac (WERROR_CFLAGS): Disable two new warnings:
-Wno-format-nonliteral, -Wno-unsuffixed-float-constants.
* gzip.h (bi_reverse): Declare with _GL_ATTRIBUTE_CONST.
(gzip_base_name): Declare with _GL_ATTRIBUTE_PURE.
