COMMENTS:  
When library functions are entered through secondary libvec linkage  
that returns a long long value, the value is returned in registers 0  
and 15. Register 0 is not saved by secondary libvec linkage, so the  
return value of a long long is corrupted when library calls are entered  
this way.  
   

SOLUTION:  
Secondary libvec linkage in cstrtl.asm was modified so that it  
preserves R0 from the caller to the called function, and then from the  
called function to the caller so that any long long values passed in R0  
and R15, in either direction, will be preserved.
