Alternatives to C/C++

Instead of sticking with C/C++ for performance consider:
1.Free Pascal -Small memory use,very fast, easy debug
2.OCaml - medium memory use, fast,very terse, functional and secure.
3.FreeBasic - very fast,easy to use, low memory use, supports QBasic code as dialect. Other Basics to consider: PureBasic/Gambas/PowerBASIC
4.Digital Mars D- fast, easy to write and debug, large library, transition from C/C++ much easier.Garbage collection can be turned off.

O'Caml has bignums and 32bit ints as well. Tag bits are a bit annoying, but they solve a lot more problems than they cause. The major problem they solve is allowing precise garbage collection, but in some other languages like Lisp, they even allow you given any data, to complerly and accurately decode it in full:
I can open any data and get a printed representation of it, or examine it in the debugger and find anything about it. No silly overflow, no silent type errors (allows safety in a dynamically typed language). If you need native ints, you can get them in good implementations.
