Maybe it would be simplest to only have mini-gmp define the mp_bits_per_limb, and let mpfr (and other applications which need this info at compile time) use a configure test like AC_COMPUTE_INT(mini_gmp_limb_bits, [sizeof(mp_limb_t) * CHAR_BIT], [#include "mini-gmp.h" #include <limits.h>]) This check should work fine with cross compilation (thanks to advanced magic in autoconf). I can't think of any portable and cross-compile safe way to instead examine the value of mp_bits_per_limb. Regards, /Niels -- Niels Möller. PGP-encrypted email is preferred. Keyid C0B98E26.
