Re: [PATCH] mpfr: Update to version 4.2.2

[Michael Tremer <michael.tremer@ipfire.org>]

Thank you.

I also updated the statically linked version in GCC:

  https://git.ipfire.org/?p=ipfire-2.x.git;a=commitdiff;h=ba4bc8da4eec7fdb43d8c0b444aec8b2343deb86

This should not be shipped, but I think we should have the same version everywhere...
