I have never heard of such systems.  There are many places where 
assignments to errno are used, so it should be safe.  You can even find 
"errno = 0;" in the glibc-2.2.4 documnetation.

The address of errno may be a result of a function call, but errno itself 
remains a valid lvalue, i.e. something that can stand on the left side of 
the assignment.
