Yes, but cygwin.dll is specifically a component of the cygwin package, which
needs to be installed before most Unix install/config scripts will run, so
it seems reasonable to keep the dll with the base set of executables, given
the way the Windows platform locates dlls.

It is on Microsoft OSs, which are, after all cygwin's host platform. So one
question here is where to strike the proper balance between conforming to
the host system's conventions and emulating Unix. I don't see any reason to
devise a custom way of locating cygwin.dll when the OS will do it for free
if it is on the PATH (which the cygwin executables need to be on anyway).

Excuse me, but I'm not all that familiar with POSIX; my Unix experience is
mostly as a user, and as a writer of fairly simple C programs and perl/sh
scripts, not as a sysadmin or serious developer. What is FSSTND, and how do
you see it as being relevant to cygwin?
