Don't agree. Each machine should provide a unique define to identify it.
You'll have to do this with the hp300 release, to get all those "ifdef hp300"
right, the sun3 port probably wants to define sun, too. Long time ago, when
we created new defines for the amigados gcc compiler, the convention was:
 #ifdef amigados
 .. do something which is specific to AmigaDOS, like dealing with
    logical devices ..

 #ifdef amiga
 .. do something which is specific to the Amiga hardware, if you have to
    further differentiate under which OS you're running, use additional

For generic code (which will probably be 99% of all code), you should NOT
use "#ifdef amiga", but "#ifdef __NetBSD__", or if it's something really
cpu related, "#ifdef mc68000".

I don't think it's the right thing to forget about the machine you're running
on, even if that makes some things easier since it doesn't let people depend
on "#ifdef amiga". I for myself will use a compiler that does define amiga,
a machine-definition just doesn't belong into a Makefile.
