On x32, I got ../sysdeps/x86_64/../i386/ldbl2mpn.c: In function ‘__mpn_extract_long_double’: ../sysdeps/x86_64/../i386/ldbl2mpn.c:72:4: error: left shift count >= width of type [-Werror] res_ptr[N - 1] &= ~(1L << ((LDBL_MANT_DIG - 1) % BITS_PER_MP_LIMB)); ^ cc1: all warnings being treated as errors This patch replaces 1L with (mp_limb_t) 1.
