Coverity flagged one magtape simulator for having fewer case breakouts
than the range of MTSE_x errors, after they were expanded for
MTSE_LEOT (listed as "V4 compatibility") and MTSE_RUNAWAY (for
Dave Bryan's implementation of erase and erase gap).
According to Dave, it turns out that MTSE_RUNAWAY can only be
returned if the magtape simulator supports and implements a density
specification and the ERASE function. The simulators Bob Supnik wrote
don't meet that criteria, so the expanded errors can't be returned.
Simply add a "default" case to the map logic returning SCPE_IERR for
unexpected cases.
Historically this functionality was reimplemented within each
DEVICE simulator often with slightly different implementations
and inconsistencies. Solving this globally within SCP required
changes in many places, but should henceforth be reasonably
managed.
As discussed in #1034
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.
In 32-bit mode, the compiler truncates constants to 32-bit.
We need LL suffix to avoid the truncation.
This behavior is contrary to the C 99 standard which defines
that constants that do not fit into long and unsigned long shall
have long long type.
The makefile now works for Linux and most Unix's. However, 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.
