That's because in these Windows versions, msvcp60.dll and msvcrt.dll
are already included with one of the applications that come together
with Windows. In Windows NT4/95/98/ME you will find versions that
don't have these and require your Firebird client to have these DLLs.

So if you only use Windows 2000 and up, it is not strictly necessary
to distribute these DLLs. However, you are always on the safe side
when you do (as Firebird itself does it, just take a look at your
"bin" folder).
