* include/types.h (GNUPG_GCC_ATTR_UNUSED): Define for gcc >= 3.5. * mpi/mpih-div.c (mpihelp_divmod_1, mpihelp_mod_1): Mark dummy as unused. * mpi/mpi-internal.h (UDIV_QRNND_PREINV): Mark _ql as unused. -- Due to the use of macros and longlong.h, we use variables which are only used by some architectures. At least gcc 4.7.2 prints new warnings about set but not used variables. This patch silences them.
