Hi Mark,
I make changes to *other* extensions. I documented the change I made
to distuils here:
http://groups.google.com/group/isapi_wsgi-dev/msg/aa11ed3058e73660
Basically I disable the step that filters the MSVCRT out of the
manifest. And then re-build the extension. I have not yet ventured
into building Pywin32. I ended up modifying distutils because of a
link to a Python bug when I searched for the error I got when loading
a C extension. | can't remember which bug and I would have to muck
with things to generate the error again, which I will do, just not
tonight :)
I have not tried using x64 all the way though, mostly because when I
got started with this project I wanted to use Psyco (which was a
miserable failure that I have given up on), which only support x86.
I'll try to do a simple x64 test and see what I get. I am on win7 so I
can select x64 or x32 Application Pools in IIS and not disrupt my
other work.
I have also determined that I have no reference to pythoncom26.dll,
only pythoncomloader26.dll, in my registry.
