out of the box on OSX 10.1. Untested by me (except for not having adverse
effects on 10.0.4) but it looks good, for now. Eventually we should not
trigger on the darwin version but test for something, but until I have
the time to install 10.1 myself I have no clue what to test on.

It would be nice if this got in to the 2.2a3 distribution.

If after calculating sys.path we do not have sys.prefix set, we loop over all path entries checking if one can point to our home directory.

enough, but may have side-effects because it preallocates a single
codeop.Compiler() to compile all statements the user enters.

Just: please review and retract/modify if necessary.

com_factor():  when a unary minus is attached to a float or imaginary zero,
don't optimize the UNARY_MINUS opcode away:  the const dict can't
distinguish between +0.0 and -0.0, so ended up treating both like the
first one added to it.  Optimizing UNARY_PLUS away isn't a problem.

(BTW, I already uploaded the 2.2a3 Windows installer, and this isn't
important enough to delay the release.)

branch (if it ever gets to the typo, the test is failing anyway).

capabilities of the Pentium FPU, so what should have been (and were on

that's unlikely, and no, I'm not adding a test case with a 2 gigabit
