Solution to problem 1:
Compile with your compiler or choice, never mind which CRT are used.
Use a 'dumpbin' program, find all references to msvcrt in the binary
DLL file. Create a dll with name "py_crt" that exports these functions
but redirects them to msvcrt71. That is, in the file py_crt.def we put
something like
EXPORTS
malloc=msvcr71.malloc
free=msvcr71.free
etc.
Compile the DLL py_crt.dll and then open your pyd file in binary mode.
Exchange all occurances of the string "msvcrt" (or any other CRT name)
with "py_crt". Now your binary should work just fine. What you need to
make sure is just that the name of the proxy has the same number of
letters as the CRT your compiler linked. So if it is msvcrt81.dll, e.g.
use something like py_crt81.dll instead of py_crt.dll.
Solution to problem 2:
[modify external references inside python25.dll to use a different runtime]
This would only work, if runtime dll's were compatibles between them,
and they are not. You can't blindly redirect a call to msvcr71.__xyz
to msvcr80.__xyz and expect that to work magically - it may have a
different number of arguments, or different types, or even may not
exist anymore.
(And what about any symbol exported by ordinal?)
