The C compiler has a flag for defaulting to signed integers (-signed).
If you have a c++ compiler from AT&T, you should be able to pass the -signed
flag on the CC command line to get cc to compile your code with default
signed integers.

This is the case with the C++ product from Silicon Graphics which should
be released in the very near future.
