Plugin questions and troubleshooting

Well fill me with propane and light a match, I got it to work!  I'm a
Cygwin junkie and unzipped the OpenSSL DLLs with Cygwin's unzip.
Apparently Cygwin's unzip doesn't seem to get permissions quite right or
something, because the DLLs did not have execute permission.  chmod +x
on them and my code works perfectly, assertion and all!  Thanks for
everyone's help.

What about the .h vs. dlopen() issue.  Anyone have any recommendations there?
