This flag was for SunOS 3 and 4 on sun3 hardware (68k). It enabled some unsafe optimizations via assembler. This hasn't actually been built since the DOS port (since the header for this was renamed, but the code in `xc.c` wasn't updated). The optimizations here made assumptions that were specific to the 68k hardware and register allocation. They aren't likely to be of much use moving forward, and we've got plenty of safe performance improvements from the last 30 years of hardware advances.

This is the implementation of the Medley Interlisp virtual machine, for a byte-coded Lisp instruction set and some low-level functions for connecting with Lisp for access to display and disk etc.
There are make file fragments that include all the flags and variables you have to set for each hardware/OS target.
- cd to the "bin" directory
- have "." on your PATH
- do "./makeright x"
It will (attempt to) detect the OS-type and cpu-type, and put together the makefile parts that it needs. It will build in ../ostype.cputype-x (for the .o files) and ../ostype.cputype for the executables.
