With the fpcmake-buildsystem it was possible to build one package from 
fpc-trunk using a fpc-release-compiler with a simple "make all". But the 
release-version of all dependencies were used.

So when fpcm-trunk uses a new feature in trunk-fcl-base, there was no 
way to compile the trunk-version of fpcm with a release-compiler.

With fppkg this all changed. Now it's always possible to compile 
(single) trunk-packages using the latest release-compiler. The command 
has been altered, though. You have to do 'fppkg build', instead of 'make 
all'. Fppkg will then compile all the packages that fpcm depend on using 
the new compiler.

This does not work if the new fpcm-package uses new compiler features 
offcourse. And the same holds for the rtl because that one is still 
compiled using the fpcmake-system.

There's one problem, still, and that's the same problem you have with 
the fpcmake-system. When the Makefile's do not support a new target, you 
have to re-generate those first using a new version of fpcmake.

The same holds with the fpmake-system. When your fpmake uses some new 
functionality that is only available in the new compiler or a new 
fpmkunit-unit, you have a problem. For this case fppkg uses two 
configurations. One to compile the fpmake.pp-files, and one to compile 
the actual packages. But that's not configured by default.
