Is "typeset" really part of POSIX shell language?  I thought 
it was a kshism, and I can't find it in The Open Group Base 
Specifications Issue 7.

I consider "typeset" less portable than "local".  As far as I am 
aware, neither "typeset" nor "local" is standardised.  "local" 
is supported by almost all shells we care about, except ksh93. 
"typeset" seems to be supported only by ksh variants, and bash.

I don't know whether pkgsrc relies on being able to use "local" in
shell scripts, but the NetBSD base system does rely on "local", and
refuses to build under a shell that doesn't support "local".
