OK, done.

There's not really a good reason for that choice.
I just started with the latest version, and later moved to older
versions, because I did not want to restrict the supported versions
more than absolutely necessary, not even in-tree.
Are there any bug-fixes that we could depend upon?

I was _very_ surprised that gmp-6.0.0 did at first work in-tree but
enabled invalid assembly code, in gmp-6.0.0/mpn/generic/div_qr_1n_pi1.c
when __arm__ or __sparc__ or __s390x__ is defined together with NO_ASM.
All in all GMP contains really much assembler code that we don't need
at all, my impression is that it is nearly impossible to test GMP
on every possible target, although it is all about mathematics.
So at least some choice would be good for us.
In that sense, I would not like to restrict the supported GMP versions
to just one version, that is not even released at this time.

Good. I updated the download_prerequsites to mpfr-3.1.4 and mpc-1.0.3
again, but left gmp-6.1.0 at the moment.
Thanks,
