Thank you for your patch.

We try to avoid using constructs like this.  Rather, we have a section in 
the Makefile which sets things like NO_IPV6=YesPlease, 
OLD_ICONV=UnfortunatelyYes, etc.

Later in the Makefile, dependent on this Makefile variable, symbols 
are defined. In the source code, we check for these symbols.

It is not only a matter of being able to reuse the same symbol for another 
platform/setup, it is also a nice way of documentation.

In your case, I suggest NO_SYS_SELECT_H=UnfortunatelyYes.

Thanks,
Dscho
