I do use Maple V/Solaris x86 (but under CURRENT only in text mode) with the
svr4 emulation. It was not really easy to find all libs and fiddle with
the loader, but it works, at least on my copy.

However, if the mere presence of svr4 in the 5.x kernel slows other
important development down, then it is a good and valid reason to axe it.
I have other ways to run this and no more objections.

Thanks for clarifying the reasons behind this decision.
