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.
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.

RESTRICTION: The PDP-15 FPP is only partially debugged. Do NOT
enable this feature for normal operations.
WARNING: The core simulator files (scp.c, sim_*.c) have been
reorganized. Unzip V3.2-0 to an empty directory before attempting
to compile the source.
IMPORTANT: If you are compiling for UNIX, please read the notes
for Ethernet very carefully. You may need to download a new
version of the pcap library, or make changes to the makefile,
to get Ethernet support to work.
