Here it is, verified against fresh trunk.

2014-09-09  Kostya Serebryany  <konstantin.s.serebryany@gmail.com>

        * locale/weight.h: add include guard.
        (findidx): un-nest, make it static inline, add parameters.
        * locale/weightwc.h: add include guard, rename findidx to findidxwc.
        (findidxwc): un-nest, make it static inline, add parameters.
        * posix/fnmatch_loop.c: include weightwc.h or weight.h depending on
        WIDE_CHAR_VERSION. Define FINDIDX as findidxwc or findidx.
        (FCT): change type of 'extra' to wint_t; do not include weight.h,
        un-nest calls to findidx.
        * posix/regcomp.c: include weight.h.
        (build_equiv_class): don't include weight.h, un-nest findidx.
        * posix/regex_internal.h: include weight.h
        (re_string_elem_size_at): don't include weight.h, un-nest findidx.
        * posix/regexec.c: include weight.h.
        (check_node_accept_bytes): don't include weight.h, un-nest findidx.
        * string/strcoll_l.c: define FINDIDX, include WEIGHT_H.
        (get_next_seq): don't include WEIGHT_H, un-nest findidx.
        (get_next_seq_nocache): don't include WEIGHT_H, un-nest findidx.
        * string/strxfrm_l.c: define FINDIDX, include WEIGHT_H.
        (STRXFRM): don't include WEIGHT_H, un-nest findidx.
        * wcsmbs/wcscoll_l.c: define FINDIDX.
        * wcsmbs/wcsxfrm_l.c: define FINDIDX.
