That's more a hack then a solution, and the real solution is simple and 
also works outside Lazarus: place the fpc.cfg in ~/experiments/etc, 
~/development/etc etc, as already suggested by Ingo. Or, even better, 
just alongside the compiler-executable. You can call 'fpc -va' to check 
which configuration file is used.
