remove no-longer-needed forward decls from regcomp.c

[Paul Eggert]

I installed this and filed glibc bug 1224.

2005-08-20  Paul Eggert  <address@hidden>

        * srclist.txt: Add glibc bug 1224.
        * lib/regcomp.c:
        (init_word_char, create_initial_state, duplicate_node_closure):
        (fetch_token, peek_token_bracket, build_range_exp):
        (build_collating_symbol): Remove forward decls; no longer needed
        now that we use prototypes.
