To reply to both...

mpfr is not actually written by GMP authors.  It is a third-party project.
Next, it's mostly written in 'C' with almost no (if any) assembly 
I think that's why it won't replace it for at least a while.
The support site for mpfr can be found at

I know that there's a lot of bugs that have been fixed.  On the site, you 
can find patch files.  I don't know the current status of mpfr.
