GCC-16 changed the default of the unused-but-set-variable warnings, which now throws an error when -Wall or -Wextra is enabled. sps_cnt is only used when USE_BLAZESYM is defined. This patch does a void cast to hint the compiler to ignore sps_cnt being unused in those cases. * https://gcc.gnu.org/gcc-16/porting_to.html#changes-to-wunused
