The errtbl.h include file, unless ERRCODE_SRC is defined
also includes attribute.h and errsym.h.
Passing an invalid argument to error(), errno() or strerror() will
set errno AND throw a math error. Before errno would be set and
an error value was returned. Before there was no way to tell if
the error value was a result of the arg or if an error detected.
Added E_STRING to error([errnum | "E_STRING"]) builtin function.
Added E_STRING to errno([errnum | "E_STRING"]) builtin function.
Added E_STRING to strerror([errnum | "E_STRING"]) builtin function.
