FYI: regex_internal.c: avoid a warning

[Jim Meyering]

Since this file is already different from libc, this shouldn't hurt...

2006-09-15  Jim Meyering  <address@hidden>

        Avoid a warning about an unused variable.
        * regex_internal.c (re_dfa_add_node): Move declaration of "type"
        into the #ifdef block where it's used.
