I don't know, sorry.

I wanted a solution that worked
on any POSIX platform -- POSIX 2008 says that
$(aaa${bbb}) is just as unspecified as
$(aaa$(bbb)) is, and I wanted to play it safe.

Part of this is my experience with implementers who
code from the spec, so that their implementations'
quirks are not necessarily those of the historical
code.
