Comment:
Replying to [comment:13 drkirkby]:
> IIRC, Singular uses -O3, which is a bit risky. Perhaps the optimiation
level can be dropped to -O2, which is much safer.
Reduced optimisation probably solves the problem. Changing to -O2 allows
Singular to build with gcc 4.6.0 on at least !OpenSolaris, but I have not
yet verified if the doctests pass. I will start a fresh build of Sage,
then run all the long doctests.
If one looks in spkg-install, one find that compiling at -O3 has caused
problems in the past, so on one platform -O0 is used.
So I suspect this is solved. I've placed a package at
http://boxen.math.washington.edu/home/kirkby/patches/singular-3-1-1-4.p5.spkg
We will need to verify if this builds and passes the tests properly on
Linux, OS X, Solaris 10 (both x86 and SPARC) with gcc 4.6.0 before I will
mark this for review. For now I'm setting to "needs info"

PS.
I reported about an hour ago to the Singular developers that I believe
they are using reserved words in Singular too (http://www.singular.uni-
kl.de:8002/trac/ticket/333).
