AFAIK MS has no requirement that you recompile your programs, so IMO you
should expect your programs to work fine. The real issue is what do you do
if there's a problem and it's related to the compiler, because VC++ 6.0 is
terminating support (mainstream support already finished, extended support
finishes Sep 2005).
