I suspect the strongest argument in favor GCC simply utilizing plane old
ASCII typographical " and ' quote delimiter characters when possible, is
that GCC is first and foremost a development tool, generating text which
just as likely to be consumed by other tools as read my humans.
Therefore GCC should arguably adopt the conventions most friendly to that
purpose; where although it may be enabled to make its output typographically
prettier, doing at the risk of potentially complicating it's subsequent use
likely isn't a good decision. As opposed to a text processing tool who's
purpose is to generate ideally human friendly text, such as intended for
documentation for example.
