I am happy to report that compile is beautiful and all tests are perfect
on FreeBSD UNIX for the RISC-V rv64imafdc architecture and a few quick
little tests look wonderful :

time for mpfr_cont_pi() was 25576800 nsecs

atan(1) * 4 may be 3.14159265358979323846264338327950280e+00

delta( atan(1) * 4 ) - pi = 0 exactly.

Funny thing.

This was on a FreeBSD build with LLVM/Clang and only the amd64
environment has a fit about an itty bitty macro issue that doesn't
really exist at all :

   https://gmplib.org/list-archives/gmp-discuss/2020-August/006556.html

Torbjörn Granlund already addressed that and there are no problems
seen other than LLVM/Clang being a bit "special".

Wonderful code!  Thank you !
