Me and William Stein think the package should not be merged in its current
state, but others disagree.

Ok, I've asked Mercurial about my p2 (which was intended to be a follow-
up):
{{{
+=== mpir-2.1.3.p2 (Leif Leonhardy, November 24th, 2010) ===
+ * #8664: Upgrade Sage's MPIR spkg to version 2.1.3
+ * Further improvements:
+ - Let MPIR select CPU-specific code generation parameters (for CFLAGS)
even
+ if we (also) pass our own (or user-specified) CC and CFLAGS; these
might
+ be used by MPFR and GMP-ECM later, too, since MPIR's settings are
recorded
+ in 'gmp.h' / 'mpir.h'.
+ Don't override user-settings (and respect SAGE_FAT_BINARY,
SAGE_DEBUG
+ etc.) though. Add '-march-native' if appropriate and supported.
+ * Recognize also lower-case 'power*' arch (from 'uname -m').
+ * Major restructuring / reformatting; more comments and messages added.
}}}
I'm not sure right now if it's ready for release, at least it is
functional as far as I remember; haven't yet committed all changes though.
Still believe we could [and maybe should] merge the p1 as is; upstream has
to be updated anyway (once again, sooner or later, but IMHO definitely on
a follow-up ticket).
