Summary: Bytecode problems with test_colorsys

Initial Comment:
Starting point: "make clean; make" in the 2.5 source tree.

"make test" hangs at test_colorsys.

Careful investigation shows that when the bytecode is
freshly generated
by "make all" (precisely in test___all__) the .pyc file
is different from what a
direct call to "regrtest.py test_colorsys" produces.

Curiously, a call to "regrtest.py test___all__" instead
of "make test" produces
the correct bytecode.

System is Linux 2.6, x86, gcc 3.4.4.

I have attached both versions of colorsys.pyc.

It's again a problem with floats.  For example, the constant 0.3 in rgb_to_yiq shows up as 0.0 in bad.pyc.  The constant 1.72986 shows up as 1.0.
