These are support functions that are currently not implemented in the 
Unix/Mac VMs (we use them to get/set the main window title directly). 
Here is how to stub them (best done in sqUnixMain.c):

char* ioGetWindowLabel(void) {return "";}
sqInt ioSetWindowLabelOfSize(void* lbl, sqInt size) {return 0;}

This should do the trick.

Cheers,
