Simba/Units/PascalScript/uPSComponent.pas
Merlijn Wajer 8558ae66d5 Simba/PS: Added extra directive ``FIXME''.
Not totally done yet. I also want to add ERROR.
Also modified the Pascalscript preprocessor a bit more, it never passed a
filename to the custom define functions. I'm open for more elegant solutions!
