Yes, I'm aware that POSIX stopped just short of standardizing it.  In
any case, its a very common trick and it works nicely on nearly all
"recent" versions of Solaris, Linux, HP-UX, AIX, etc.  In fact, you'll
have a difficult time finding a Unix or Linux OS released after 1999
that doesn't support that syntax.

And please don't submit some stripped-down embedded system as a counter
example.  I don't doubt their existence.  ;-)
