The C standard recognises the problems with errno and doesn't require
it to be an identifier.  It just has to be a macro that produces a
modifiable lvalue.  So a threaded implementation can do something
like

   #define errno (*__thread_errno())

where __thread_errno() returns a pointer to a per-thread variable.
