The usual C runtime lib problems as it embeds Python, and also calls problematic
functions in the rumtime lib, so it should use the same lib as Python itself.
If you build a pure Python bdist_wininst installer, which can be used to install
into Python 2.3, 2.4, 2.5, and more versions, the postinstall script (if any) does not
run correctly if Python uses the wrong runtime lib.

I have not tried to build a 64bit runtime stub for bdist_wininst, that's the
only reason so far. It could probably be solved.

Well, bdist_wininst had a sucessful live, I see no problems if it is
replaced with something else - be it eggs or bdist_msi.
