Yeah, I would say the chance that an optimization bug in the compiler used to build your new compiler will cause the new compiler to generate faster code is rather small... > > To put it another way, if you recompile (the same version of) a library, > you don't have to recompile the applications that use it. > > In my case, my application makes heavy use of the C++ Standard Template > Library (STL).

Unfortunately, if you want to take advantages of newer STL versions, you will have to recompile your applications, since the STL is just a set of header files included in your application (not that the STL changes much). Changes in the C++ Standard library of course will benefit you without recompiling your application. Leendert -- [EMAIL PROTECTED] mailing list
