Wanted to rant.
AxImp really stinks when it comes to handling type libraries that use importlib (ok, typelibraries built from IDL that uses importlib).
The workaround is so pained, so contorted that it deserves a blog entry. More on that later. Nothing like having to write a program whose sole purpose is masking the error returned due to a bug in another program. The buggy program is aximp. Masking the error allows the visual studio 2005 prebuild event to not fail. Ugh.
