I think these might as well live in the sgi toolset.

The slash notation is currently used to get two different values of a
single feature. Legal usage would be:

<sgi-abi>n32/n64

Seems bug-ish to me.

That's not fully implemented yet; you wouldn't stand a chance :-(

Are the different values of <sgi-abi> link-compatible with one another?
I don't think so!
That sounds dangerous to me.
