as we all know, it's high time now to adjust the minimum supported
gmp/mpfr/mpc versions for gcc-7.
So this attached patch is now targeting at only supporting the currently
latest relased gmp-6.1.0, mpfr-3.1.4 and mpc-1.0.3, instead of trying
to support all previous versions, especially in-tree, but also without the
in-tree configuration the previously used versions are really creating
trouble nowadays.
For in-tree builds, requiring the latest version makes sense to me. When
building gcc with a pre-installed gmp/mpfr/mpc (say the one provided by
your linux distribution), that's much more painful, and the benefit is not
as clear. What "trouble" do you have in mind?
To support gmp-6.1.0 in-tree we have to set AM_CFLAGS=-DNO_ASM
as already done with mpfr. This was already discussed recently on this list.
Note that gmp-6.1.1 is supposed to be out any day now and will not require
-DNO_ASM anymore.
