Setup.exe or msvc.dll?  I guess either way, cygcheck should tell you.

No, it's really a quite different thing.  MS specifically declares msvcrt.dll as redistributable.  It's intended exactly for this purpose.

That may in fact be true, now that I think of it.  ISTR that when I was working on the Wizard style GUI, we made the decision to allow setup.exe to depend on a post-Cretacious-era common control DLL or something.  The common control DLLs are not redistributable.  I'll check on this tonight; maybe we'll get lucky and whatever is needed actually is redistributable.
