I am running an experimental Mach system (4.3BSD compatible) on an 
HP 9000/s300 workstation. After some enquiries on how we might get C++ for 
this O.S./hardware configuration, we decided to port AT&T C++ 2.0 ourselves. 

However, according to the release notes for C++ 2.0, a prerequisite is a C
compiler and linker that support structures as legal arguments to functions
and as return values from functions, as well as supporting structure 
assignments. The current C compiler on our Mach system doesn't support these
requirements. Does anyone know to what extent AT&T's C++ 2.0 depends on 
these facilities and under what conditions we are likely to encounter problems.
Alternatively, does C++ 1.2 require this compiler support? 

Also, any alternative suggestions for how we might get C++ for this 
O.S./hardware combination, or how we might get/port a C compiler that supports 
these more recent C enhancements.

	Comments or thoughts appreciated,
