In the mean time, I added another upstream fix to PARI: issquarefree(0)
used to raise an error instead of returning 0.
Three tickets, including the gcc spkg (hence, OS X 10.7 support) depend
on this, so I consider it an important ticket.
So, please review:

Two patches need to be added to the PARI sources:
1. GCC 4.6.3 miscompiles src/language/init.c on OS X 10.4 PPC (32-bit),
because of a problem with pointer arithmetic in stack_base() called in
pari_init_functions(). There is an easy work-around by reordering some
code in the PARI sources. Related to #12369.
2. PARI's ispower() function gives wrong results when applied to
negative numbers. Related to #12116.
Please review the PARI spkg at:

Thanks,
