Comment (by rwbarton):

 Replying to [comment:53 rwbarton]:
 > Another suggestion is to add to the repo a big patch file that we apply
 to the untarred GMP 5.0.4 source to turn it into the GMP 6.1.2 source. (We
 apply some other patches after unpacking already.)

 I was unable to create such a patch smaller than 1MB compressed, even by
 importing the unpacked tarballs into git and creating a patch with `git
 format-patch -M -B -C -C -D`. So this doesn't seem like a promising
 approach.
