Subject: factor: port to --without-libgmp
X-Git-Tag: v9.0~215
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9462c1202d91e007d634e9f8e60da7ed2c71e328;p=thirdparty%2Fcoreutils.git

factor: port to --without-libgmp

* src/factor.c (mp_factor_using_division): Use mpz_fdiv_q_2exp
instead of its no-longer-documented mpz_div_2exp alias.
(print_factors): Use mpz_out_str instead of gmp_printf.
