The names are msvcxxxx.dll and specifically msvcrtxxx.dll

The question I was trying to answer is why code compiled with VC2010 
would act differently (work with 3.2 or not) on xp and win7. When 
running of win7, the code can use system calls that did not exist in xp. 
When running on xp, the code must do something different (probably 
slower, if not stop). Exactly where the different paths reside is not so 
important.
