'''This is an upstream problem with PARI/GP'''
Upstream report: [http://pari.math.u-bordeaux.fr/cgi-
bin/bugreport.cgi?bug=1099]
The "rnfkummer" test in PARI's {{{make test-all}}} fails on the following
systems:
* PPC OS X 10.4
* Linux PPC 32-bit
* Solaris SPARC
For example, on a PPC Mac OS X 10.4:
{{{
GP/PARI CALCULATOR Version 2.4.3 (development svn-12594)
PowerPC running darwin (PPC/GMP-5.0.1 kernel) 32-bit version
compiled: Sep 8 2010, gcc-4.5.1 (GCC)
(readline v5.0 enabled, extended help enabled)
}}}
I get a failure in rnfkummer (both sta and dyn), I am attaching the dif
and the output of Configure.

Comment(by leif):
Jeroen, could you also extend the message printed when
{{{SAGE_TUNE_PARI=yes}}} to strongly recommend running PARI's test suite
after tuning? (We could in principle do that automatically from {{{spkg-
install}}} as well, but that's IMHO not a good idea since it then might
get run twice, and also doing so wouldn't fit Sage's build/test process.)
As mentioned somewhere else (#9343?), one of PARI's self-tests fails
''after "successful" tuning'' on a Pentium 4 Prescott running Ubuntu 9.04
(gcc 4.3.3). I've yet only put a comment on the wiki page; will open a
ticket for that later.
----
I'd prefer prepending {{{./}}} to {{{Configure}}}, since this will give an
''appropriate'' error message in any case where {{{src/Configure}}} does
(for whatever reason) not exist. (Otherwise {{{bash}}} would then attempt
to find it in {{{$PATH}}}, which might cause weird behavoir.)
----
While adding {{{-fno-common}}} on MacOS X 10.5 and 10.6, too, is perhaps a
bit odd, it doesn't hurt; otherwise one should look for ''Darwin 8''
(10.4) with {{{uname ...}}}. (I currently don't know the exact string; the
relevant part should be the same on PPC 10.4.).
