So, given how limited the problem is, I don't think the alarmist Subject
was really called for.  Anyone reading the subject would think that
there was something seriously wrong with Cygwin 1.7 and that is not the
case.

I mentioned that things still work this way (as they have for the last
eight years) when I announced the speclib rewrite and you said:

"Yes, multiple import tables for the same DLL Name are definitely OK; if MS
ever do anything to change this, we'll have real problems with auto-import."

Did you miss adding an "as expected" in the above paragraph?
