* libguile/bytevectors.c: * libguile/goops.c: * libguile/instructions.c: * libguile/numbers.c: * libguile/random.c: * libguile/read.c: * libguile/vm-i-scheme.c: Fix a number of assumptions that a long could hold an inum. This is not the case on platforms whose void* is larger than their long. * libguile/numbers.c (scm_i_inum2big): New helper, only implemented for sizeof(void*) == sizeof(long); produces a compile error on other platforms. Basically gmp doesn't have a nice interface for converting between mpz values and intmax_t.
