So, this would be a change in current mingw.org behavior.  I *was*
under the impression that this workaround for the old "can't pass
empty strings across DLL boundary" problem[1] was no longer necessary
in the gcc-4.x era, but I haven't tested the proposition.  Was I wrong
about that?


Yes.  If you read last comment of the thread you are citing, then you
would notice that for static-libstdc++ version the issue is still
present.  So to allow users to use also static-libstdc++ variant, this
option is still necessary.


Thanks for the clarification.  So, we (mingw.org) really should have
been using this all along, to support users of -static-libstdc++


Please let me present an opposing view.

On the one hand, according to comment 4 of [1], by using --enable-fully-dynamic-string, all other users will miss a very good optimization. On the other hand, these users of -static-libstdc++ are mixing shared and static libraries, which isn't a good idea in general anyway, is it?
