-----------------------+----------------------------------------------------
On all 32-bit linux systems, if I set SAGE_FAT_BINARY in sage-4.2.1.rc0, I
get an internal compiler error when building PARI. Since PARI hasn't been
upgraded in a while, I think this is the fault of MPIR:
{{{
gcc -c -O1 -Wall -fno-strict-aliasing -fomit-frame-pointer -I.
-I../src/headers -I../src/graph -o
plotport.o ../src/graph/plotport.c
../src/graph/plotport.c: In function 'rectticks':
../src/graph/plotport.c:469: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-4.3/README.Bugs> for instructions.
make[3]: *** [plotport.o] Error 1

Recommendation: we revert to
http://wstein.org/home/wstein/patches/mpir-1.2.p8.spkg
so we can release sage-4.2.1. This is a subtle error and should be
reported to the MPIR dev's.
Note though that I can *build* sage with SAGE_FAT_BINARY="no", then
rebuild MPIR with SAGE_FAT_BINARY="yes", and that seems to get around the
compiler error. But I haven't tried running the full test suite, and the
fact that upgrading or rebuilding PARI would then result in an internal
compiler error is *not* encouraging.
Another alternative would be to use GMP instead of MPIR for our general
distribution version. It might work better in this regard....
