We will fix the compilation, but since we have several users and
developers who regularly compile on Sun, I have to suspect they're not
using whatever the appropriate option is: the last change to that file
was in Sept 2004 according to the ChangeLog.

Does the feature actually work?

This is weird, too; I'm pretty sure we have people building regularly
on recent Solaris.  Any ideas why your environment would elicit this
bug, when (AFAIK) it doesn't occur for others?
