Thanks Mattias, this helps a lot.

Where does the command line parameter --pcp play a roll?  Different
shorcuts on the desktop with pre-configured FPC paths and compiler settings?

Can we define our own "custom macros" in the IDE? What is the "CodeTools
defines editor" used for? Is that maybe for custom macros?

Ah, I didn't know source directory supports macros. Another plus point
for having Mantis report #14558 implemented. :-)

Yeah, I think I do that correctly - not sure if it's the "fpc way" though.

--------[ /opt/fpc_2.3.1/go46.sh ]----------
cd src
make clean
make all PP=/opt/fpc_2.2.5/bin/ppcx64
make install INSTALL_PREFIX=/opt/fpc_2.3.1 PP=/opt/fpc_2.2.5/bin/ppcx64
----------------[ end ]----------------

I have similar scripts for 32-bit compiler and unstable trunk. And I
always use the FPC 2.2.5 stable release to build newer releases.
