AIO works fine, I think, and is happy with SMP.

Hi,
I have written some code in C++. However, I want to run it on an old
mainframe machine, which a C++ compiler is not available.
I know that the old g++ is a C++ to C compiler. Does anyone know which
version it is? Also, anyone knows other C++ to C compilers?
Thanks,

The original Stroustrop ATT C++ complier called cfront was a front-end C
