Wow, that seems very inflexible. Is this a design decision?

Why would 1 cygwin.dll care about another on the system that has nothing
to do with it?

I have N different versions of our product installed on my windows
machine, and each has a slightly diffferent vresion of qt.dll. This
isn't a problem at all. What's limiting Cygwin?

BTW, this worked before I upgraded cygwin. So it is at least possible if
they are the same version?

Thanks,
