Yes, POSIX defines it indeed.

This is potentially dangerous. Imagine the following code snippet:
switch (rc)
{
case ECANCELED:
do_it();
break;
case EINTR:
do_that();
break;
}
If we define ECANCELED to EINTR, cc will report a `duplicate case value'
error.

Well, it is possible. We could use our MU_ERR_BASE for that, e.g.
#define ECANCELED (MU_ERR_BASE+300)
However, I'd like to find out more meaningful alternative.
