Bug #14780: In function ‘tr_trans’: warning: unused variable ‘old’

I get the following warnings when compiling string.c:

compiling string.c
string.c: In function ‘tr_trans’:
string.c:7038:10: warning: unused variable ‘old’ [-Wunused-variable]
   size_t old = max + termlen;
          ^~~
string.c:7111:10: warning: unused variable ‘old’ [-Wunused-variable]
   size_t old = max + termlen;

The reason seems to be that the newly introduced macro SIZED_REALLOC_N ignores its last parameter in some versions.

Can you try r63487? It uses the MAYBE_UNUSED macro which I hope
works for your platform. Thanks.
