[fpc-pascal] [OT] GPL Lisence help

[Jorge Aldo G. de F. Junior]

The engine is a integral and needed part of a car, yet the engine
design and production is not necessarely part of the rest of the car
production (In very old times, companies like mercedez built only
carriages, benz built engines + chassis, eventually they decided to
merge to produce both together, something like that if i remember).

The idea is that i am perfectly entitled to design something around a
product of other company, without infringing their intellectual
property.

Accessory or obligatory use doesnt matter, as long as the code is
distributed separately and each part is clearly identifiable.

Regarding the difference between system libraries, how can you
differentiate among non-system libraries and system libraries ? This
is quite arbitrary.

APIs are not copyrighteable.

This was the whole concept around the Google vs Oracle case.
