If mylib.dll depends on cygwin1.dll then this will not work. To load
the Cygwin DLL dynamically requires special attention, as described in
the FAQ: <http://cygwin.com/faq/faq.html#SEC102> and recent mailing list
threads, as this is a very recent ability.
If mylib.dll does not need functionality from Cygwin, then you should
compile it with -mno-cygwin, and it will be dynamically loadable without
extra care just like a standard windows DLL. More information about
this is at <http://www.mingw.org/MinGWiki/>. If you go this route you
are no longer using Cygwin so your questions should really be addressed
to the mingw list.
