I started using this today, and so far it looks very good, thanks.

Isn't it true that this ABI change only affects static linking with
third-party libraries?  AFAIU, a DLL built with the old MinGW runtime
has opendir/readdir etc. statically linked into it, and so using such
a DLL from a program built with the new runtime will not present any
problems, unless the functions exported by the DLL accept the DIR and
dirent structures as arguments.  Is that correct, or am I missing
something?
