[fpc-pascal]compiling CLX with FPC and Classes.Inc

[Den Jean]

Hi,

I'd like to use fpc with FreeCLX, but when compiling I stumbled on the
fact the SListIndexError is not known because {$i classes.inc} is included
after implementation and not just behind interface.

I hope this an error ? 

In kylix/source alike constants (constse.inc) are defined in 
RtlConsts and used everywhere.

kind regards,

Den Jean
