I partially agree with Niels, mini-gmp API is not fully compatible with
gmp's, but, on the other side, we should give some way to detect
mini-gmp's version...

Paul pointed us to a file in the development tree of MPFR, with a
compatibility-wrapper for mini-gmp. Will it work with the next release?
It bases its detection of functions to be implemented on lines like
#ifndef mpn_scan1
but in mini-gmp we do not #define the name of the function (as we do in
GMP). A defined __GNU_MINIGMP_VERSION might give an easy way to
conditionally define a block of missing functions...
