This one unused var warning brings down the entire1 -Werror builds of SPARC.
I tested this with SPARC and it fixed the build.
$ env \
ATDM_TRIL_SPARC_BUILDS_LIST=cee-rhel6_clang-5.0.1_openmpi-1.10.2_serial_static_opt \
ATDM_TRIL_SPARC_USE_OFFICAL_INSTALL=1 \
ATDM_TRIL_SPARC_ATDM_USE_INSTALL_DIR=/projects/atdm_devops/trilinos_installs/2019-03-30 \
ATDM_TRIL_SPARC_SKIP_NATIVE_BUILD=1 \
./sparc-tril-dev-scripts/run_builds_and_tests.sh
and it passed with:
97% tests passed, 7 tests failed out of 278
