1 About C++ porting on transputer
  Our research group is involved in development of environment for
  transputer-based machine. We run Helios as our basic system support.
  We are porting C++ (2.0) to be run with the helios C.
  This C compiler is almost C-ansi but the C++ compiler optimizes some
  declarations which are not accepted by the Helios C, for example
	struct A { ... }
	struct B { A* a; }
	B b;
  The ATT C++ (2.0) compiler does not generate the A structure since just
  a pointer is used. This botches the Helios C compiler.
  So we have modified the ATT compiler to cope with Helios C.
  Some other minor problems occur, requiring minor extensions.
  Other problems include :
    - the C Helios does not have an independent preprocessor stage, we have
      ported the Gnu-CPP to run in front of the ATT-cfront.
    - _main is an Helios function
    - ...

  I can't distribute these sources since ATT copyrighted but if some
  vendors are interested, business could be business.

2 About cross-compiler
  We have a cross-compiler Sun -> Helios. Our header files are just
  mounted by NFS and we use the -I directive.
