I think such a library would be very useful. But as Ilya Bobir
mentions, it is very similar to Microsoft's SafeInt, developed by David
LeBlanc. Did you have a look at his library before?

Interesting! How would you use hardware to check int overflow?

Indeed. Note that Microsoft's SafeInt will be shipped with MSVC 2010.
Actually, Visual Studio Beta 1 already has it placed at "C:\Program
Files\Microsoft Visual Studio 10.0\VC\include"
There's also a freely available version of David LeBlanc's SafeInt at
Microsoft's open source website, www.codeplex.com/SafeInt BTW, I did
help a little bit to get it compiling on GCC. :-)
