Different people report different results. Python still has the
machinery to link with -lcma, and for some people, it reportedly
figured that out correctly. For some people, the 2.2 configure
apparently fails because it picked up the wrong preprocessor - I don't
know why that would happen.

Some people see crashes (in the testsuite) due to unexpected
signals. I believe that these originate from the fact that the
user-level thread library uses signals in certain cases, and this may
interfere with signal handlers that the signal test installed.

Of course, this is pure guesswork.
