The point is that no matter what language you write it in, the
limitations on how much memory your program can have are determined by
the system, not by the C language, or any other language.

If you want to know whether it is possible to allocate more memory
under Windows, ask in a Windows group like
news:comp.os.ms-windows.programmer.win32. For the same information
about Free BSD, ask in a BSD group or mailing list.

This is not a limitation of the C language, so the language can't tell
you how to overcome it, if indeed you can at all. Maybe you can't.
