errno macro is not compatible with equal named c++ members

[Georg Maaß]

C macros are not compatible with equal named member functions or member
properties of c++ classes.

If I spend a errno property or method to a class there is no more
distinction between the member property and the macro, because I can't
use a scope operator for the macro. Instead of macros I would prefer
variables and methods bound to a namespace like error. This would give
me the ability to access the error information provided by some C func-
tions also inside classes, that define there own equal named property to
store that retrived information.

If your provide the errno as a predefined global variable instead of a
macro, the g++ developers get a chance to wrap a namespace around it.

Greetings, Georg
