Source for libgmp 10.4.1

[Lucas Gonze]

Hello libgmp world.

I wonder if the community has any ideas about how to get to the state of
the source code at or near the 10.4.1 build. I have not yet been able to
find a tag or release in the Mercurial repo, though this may be due to my
limited skills with Mercurial.

This is for the purpose of complying with the requirements of the GPL. My
purpose is helping a developer who linked with that build in making source
available.

Thanks in advance for any thoughts.
