That's going to bust when out_string contains stuff that does not fit in
I don't remember how this was addressed in the rest of distutils.

This is change in the code object internals in Python 3, and 2to3 doesn't
seem able make the conversions automatically. I don't remember exactly
how it goes, but there are other instances of this in Numpy -- need to do
one thing on Python 2 and another on Python 3.
Anyway, here it seems like the `inspect` module should be used -- no need
to go mucking with in the code objects to just find the number of
arguments for a function.
Nobody has tested this part of the distutils code on Python 3, and indeed
it does not have any tests, so it's not a surprise that stuff like this
is left over :)
