I'm not sure what the use case was. I guess one could add an mpq.c
source file to the mini-gmp directory with mpq functions (that seems
like an appropriate level of modularization for this).
But another alternative with less code duplication might be to try to
build the existing mpq code, using mini-gmp for the underlying integer
arithmetic? I've neither hacked or used mpq, so I'm not sure how hard
that would be.
From a quick look, I note that the total linecount of mpq/*.c is
considerably less than mini-gmp.c, and that the code uses very few mpn
functions, mpn_cmp, mpn_mul, mpn_tdiv_qr, mpn_get_d, mpn_rshift. Of
these, mpn_get_d and mpn_tdiv_qr are not provided by mini-gmp.
