I believe you are correct ... I'm being cautious in recommending a
recompile of everything, to ensure ABI consistency.

Of course, anything we distribute ourselves should be appropriately
recompiled as a matter of course.  Unfortunately, current constraints on
my time mean that I cannot attend to this myself, at present, and I
don't know when I may be able get around to it, in the foreseeable
future.  Reports of any identified issues, which may be related, will be
appreciated; if any other MinGW developers can address such issues, in
the short term, that too will be much appreciated.
