I am aware, the point was Alan what said ''We've removed a bunch of code using those defines already (I've mostly
used #unifdef to do so, with manual editing only for special cases).

We still need the #ifdefs for sun & sparc, but prefer the __sun & __sparc
forms so they still work in strict standards compliance mode. ''

I was look for a common set of defines and systems that are defined in all libraries.
Obviously, it is a for a user no help if FOO is defined in one and removed in others.

more over, i would argue for one define per system. If need this can handled if #ifdef.
Now i would like to see what ancient code can be removed.
