Well, IMO, the format of binary files generated by VC2003 andProblem arise with the C runtime, not with object file format. In
VC2005 is compatible in most cases.
particular, python uses the C api for file handling, and the standard
C is definitely not ABI compatible within VS versions.
I strongly advise you against using VS 2005 (with the binary python;
if you build python by yourself, then no problem; I don't know if it
is possible to build python with VS 2005). You *will* get crashes in
many cases.
