New description:
As the summary says. Also, mpir-2.4.0.p5.spkg fails self-tests, moreover
it's old.
Upgrading to 2.6.0 fixes both issue.
Here are some (preliminary?) spkgs of MPIR version since 2.4.x:
* [http://sage.math.washington.edu/home/palmieri/SPKG/mpir-2.5.1.p0.spkg],
* [http://sage.math.washington.edu/home/palmieri/SPKG/mpir-2.5.2.p0.spkg],
* [http://boxen.math.washington.edu/home/jpflori/mpir-2.6.0.p0.spkg]
(based on Cygwin fix of #12115).
The different spkg were upgraded to the quoted versions, with files
removed as described by SPKG.txt, and patches rebased except the yasm
patch which seems no longer necessary was removed.
Current concerns:
* `quote_asm.patch` patches files of the form `*.asm`. Should it also
address files of the form `*,asm`? There are two such:
`mpn/x86/p6/addmul_1,asm` and `mpn/x86/p6/submul_1,asm`.
* compilation with clang might fail on OSX
In addition to using one of the above spkg,
apply to SAGE_ROOT [attachment:trac_13137-stopgap.patch].
This also requires the fixed LinBox spkg from #13755.

Comment:
The discussion about headers inclusion at mpir-devel can be read at:
https://groups.google.com/d/topic/mpir-devel/m__z0PR_wBw/discussion
Anyway, even if MPIR puts in a solution at some point, I think LinBox must
be fixed anyway.
So #13755 makes sense and I'll put it as a dependency here.
The discussion about sage.math.washington.edu failure (which is highly
likely to be unrelated):
https://groups.google.com/d/topic/sage-devel/Tmg6nA1eWGk/discussion
I guess what must be done now is to retry some builds on different
archs/compilers combinations (to check the clang thing for example)
because this spkg is highly sensitive to that, and then we could launch
the patchbots (or launch them directly but I don't know how to do that,
nor how to get their results), so I put this as need_info now.
We should also decide what to do with the "history" of the spkg.
For now, I've based the spkg on the one from #12115, mentionned in
SPKG.txt with an hg commit plus an hg tag done by myself (if #12115 gets
merged before that one, I guess we'll do a "proper" rebasing), then added
mentionned of 2.5.2.p0 by John in SPKG.txt but without hg commit or hg
tag, and finally mention of 2.6.0.p0 in SPKG.txt with an hg commit but no
hg tag, assuming it will be automagically by Jeroen scripts.
