This should be corrected. I'd changed the Cygwin port to use 'gcc -shared -Wl,--export-all-symbols' specifically to address export symbol and other loader related issues under Cygwin. Apparently my changes never made it back into the source.

Don't know. I've only recently pulled it and started my porting.
