CCL doesn't use Cygwin libraries (both to avoid dependencies and because
of licensing concerns which may or may not still be valid - at one point,
Cygwin was GPLed, IIRC.) Its kernel can be built with the Cygwin toolchain
(at least with versions of the Cygwin toolchain that support the -mno-cygwin
I don't know what happens if you try to dynamically load Cygwin libraries
into a non-Cygwin application. Whatever it is is (a) likely to be unpleasant
and (b) very likely what you're seeing.
I suppose that (c) would be "doesn't have anything to do with CCL, specifically."
(As you seem to note.)
If you can find or build non-Cygwin versions of the libraries that you're trying
to load, you'll likely find that that works better.
