The same is true if an API function xyzzy() is only available in a Linux setting but not in an HPUX setting. If may compile, but it will never link. To work around this, you'd then have to link with a bunch of stub functions under HPUX, just to make the link phase successful. This is a very ugly solution for something that is "engineered", IMHO. It is also potentially dangerous, unless of course you pepper all of your stubs with "raise Program_Error" or some such. -- Warren W. Gay VE3WWG http://ve3wwg.tk
