These changes facilitate more robust parameter type checking and helps
to identify unexpected coding errors.
Most simulators can now also be compiled with a C++ compiler without
warnings.
Additionally, these changes have also been configured to facilitate easier
backporting of simulator and device simulation modules to run under the
simh v3.9+ SCP framework.
Very minor in all cases, but the strange case of swtp_cpu.c
This module used expressions of the form:
PC = ++PC & ADDRMASK;
Officially, the C language says that expressions which modify the same variable in more than one place have undefined behavior.
These were changed to the legal form which performs the desired action:
PC = (PC + 1) & ADDRMASK;
The makefile now works for Linux and most Unix's. Howevr, for Solaris
and MacOS, you must first export the OSTYPE environment variable:
> export OSTYPE
> make
Otherwise, you will get build errors.

The save/restore format has been updated to improve its reliability.
As a result, save files prior to release 3.0 are no longer supported.
The text documentation files are obsolete and are no longer included
with the distribution. Up-to-date PDF documentation files are
available on the SimH web site.
