Useful tips before using platform defines

- http://www.stack.nl/~marcov/porting.pdf - general porting guidelines
- if you need to cast a pointer to an integer for arithmetic or you want to provide a spare field (like tag in Tcomponent) that may be used to store a pointer use ptrint as signed type, or better ptruint as unsigned type.
