[fpc-pascal] from fpc 2.6 to 3.x

[Marc Santhoff]

Hi,

which are the main changes when upgrading fpc from 2.6.4 to the current 3.x
release?

I remember having tried once for building ppcrossarm. That worked. When
compiling my old stuff in lazarus on x64 native it left me with a really big
mess. So big I switched back to 2.6.4 without taking any notes...

Since I do not want to do that again I need to know how to prepare properly.
I've ssen the release notes in the wiki [1], but there is no comparison
between the two lines of development.

TIA,
Marc
