Subject: [PATCH 05/17] libdecnumber/dpd/decimal64: Fix compiler warning from
 Clang 15
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Clang 15 from Fedora 37 complains:

 ../libdecnumber/dpd/decimal64.c:620:8: error: variable 'n' set but
 not used [-Werror,-Wunused-but-set-variable]
   Int  n;                     /* output bunch counter */
        ^
 1 error generated.

Remove the unused variable to silence the compiler warning.
