Could there be a patch file created for
or something similar?  I am thinking that a number of small and
reasonable fixes are being applied to the code base but the release
tarball is locked in time without a patch file to be seen.  The mpfr
folks tend to provide a patch file which addresses some of their
updates and fixes and I am wondering if gmp folks have considered
this ?
