I was wrong, there ARE problems!
The ported code starts up fine on Raspberry Pi, but as soon as I try
to connect a TCP socket connection to the device the program crashes
No dialog or anything, it just disappears from sight!!!

As I stated I have created the program from scratch on Windows7 using
FPC/Lazarus (64 bit version) and on Windows it works just fine.
It uses Indy10 for TCP communications.

Then I zipped up the sources and put them on the RPi3 box where I have
FPC 3.0.4 and Lazarus 1.8.4.
Opened the project in Lazarus and compiled and ran the program.

So I have NOT edited the code for any Win/Linux differences for
example, is that needed?

For example in some console apps I have made also for both Windows and
Raspbian I have this in the lpr file:
    {$IFDEF UseCThreads}

If that is needed also here, where should it be put?
