The configuration with mini-gmp, when GMP is not installed, doesn't
compile cleanly.  First, compilation in lib/ emits this warning:

    CC       mini-gmp-gnulib.o
  mini-gmp-gnulib.c:28:10: warning: unknown option after ‘#pragma GCC diagnostic’ kind [-Wpragmas]
  # pragma GCC diagnostic ignored "-Wsuggest-attribute=malloc"

Next, compilation in src/ yields further warnings:

  data.c: In function ‘bignum_arith_driver’:
  data.c:2811:9: warning: assignment from incompatible pointer type [enabled by default]
     accum = &mpz[0];
	   ^

	 accum = &mpz[0];
	       ^
  data.c: In function ‘Flogcount’:

      nonneg = &mpz[0];
	     ^
