Log Message:
-----------
regcomp_trie: prevent wordlen value not used warning
This occurs with clang-17, and possibly other versions:
regcomp_trie.c:667:13: warning: variable 'wordlen' set but not used
[-Wunused-but-set-variable]
667 | U32 wordlen = 0; /* required init */
| ^
This happens because while the first loop in Perl_make_trie calculates
wordlen, mostly via the TRIE_READ_CHAR macro, that calculated value
isn't used.
The later loops do use the value of wordlen via the TRIE_HANDLE_WORD()
macro.
Unfortunately the use in TRIE_READ_CHAR() means we can't remove
this first definition, so suppress the warning.
