Hmm? In what way does bash violate POSIX? I can't think of a thing, and
bash is generally very careful not to.

Well, this isn't entirely fair to Makefile-writers, who honestly cannot
do this. But these are exactly the ones who, since they can't "choose"
their shell, should never be assuming anything beyond POSIX, unless they
want to explicitly invoke $(shell /bin/bash -c ...) :-/
