This is wrong. I'm not exactly sure what you're trying to say here, but
there is no make I know of that accepts exactly that syntax. That's
_shell_ syntax. Maybe that's what you meant by part of the
standard... it's certainly syntax that's valid in POSIX shell, and also
in almost all pre-POSIX Bourne shells, but it's not make syntax of any
flavor.
You mean:
PERLPREFIX = $${PREFIX:-/usr}
SITEPREFIX = $${PREFIX:-/top}
^
(note the escaped dollar). You want the _shell_ to expand this
variable, not make.

That's because it's an invalid syntax...

We'll glare disapprovingly right back atcha! :-P :)
