I've been looking into this, but -1 seems to be the correct way for
the implementation to report that it does not impose an arbitrary
limit. The specification of limits.h calls for these macros to be
defined with "minimum maximum" values (the lowest limit the
implementation might impose) while sysconf may return a more-relaxed
value. It's not 100% clear whether it's intended that sysconf return
-1 for them, but it seems valid and reasonable. I'd like to hear other
opinions on the matter.
