Additionally see this link
https://gmplib.org/list-archives/gmp-devel/2014-April/003778.html
which is one of the many results of Googling "latest stable gmp that
works with mpfr, mpc."  Finding the correct information about which
versions work with others is a game of sifting through lots of
mis-info....i'm lucky that the link hsppens to mention version 3.1.0
of mpfr is needed to work with gmp 6, but what about mpc? I could just
wing i...download mpfr 3.1.0 and gmp 6 and cross my fingers...but, if
it doesn[t work, downloading multiple versions of *any* source to
re-do in-tree builds is kind of a pain on an Android device...
