I've started converting a large amount of MSC 5.1 code to 6.0, and ran
into a wall.  

My code sets errno to private values (retubned by a custom driver).
In 5.1 this was no problem since errno was just an extern int.  In 6.0
(I assume to facilitate threads) errno is defined as a function.  I
cannot find anything in the documentation that lets me set the errno
value.  

The errno.h header file claims errno is set by "system functions".
Does anyone know how to set errno in C6.0?
