The C code didn't have -Werror enabled (when configured) and didn't enable the full set of warnings we would want. However OCaml-C bindings commonly declare functions which are called directly from OCaml, eg: external parse_memory : string -> doc = "v2v_xml_parse_memory" value v2v_xml_parse_memory (value xmlv) These do not require prototypes as no other C code will call them, so we have to switch off the GCC -Werror=missing-prototypes flag for these files. Also fixes some confusion between _CPPFLAGS and _CFLAGS.
