Sorry, that's not possible with cygwin.  You always need the DLL.

Even if it was possible, you'd still need to provide the sources to the
library since Cygwin is GPLed.

I'm not sure I understand the question.  It's not a matter of what your
target audience understands.  It's a question of the cygwin licensing
terms, which are basically the GPL.

You don't have to force people to download sources but they have to be
available for those who want them.  Again, if you are not distributing a
copy of the Cygwin DLL you don't have to provide sources for it.  The
only requirement is that you must make the source code available for the
program (mysql) which is linked with the DLL.  It sounds like you are
already doing that.

However, again, if you are providing the just the cygwin DLL as a binary,
you have to change that.  You need to provide the sources, too.

I am obviously not a lawyer but these are the requirements as I understand
them.  The GPL is available at the FSF web site, if you want to take a
look at it.
