It's already in the reserved namespace, so no need to reserve it
explicitly.  (The last sentence before the "Macros" heading says
"Targets with names consisting of a leading <period> followed by one
or more uppercase letters are reserved for implementation extensions."

That name isn't reserved, because it has an underscore.

However, SunPro make seems to have several special targets with an
underscore, so it's possible underscore was left out of the reserved
name space by mistake.
