Hey.

The GCC i compiled is 4.8.2, with ObjC support - and with that I compiled the 
libobjc for gnustep form github. But that didn’t affect the GCC part afaik. 
What does the switch "-fobjc-runtime=gnustep-1.7“ mean - and from where does 
GCC know about gnustep-1.7?
Im just curios, as I am no compiler junky ^^;

Kind regards,
Ingwie
