cygwin1.dll is a big dll to distribute. it requires GPL compliance, which 
prevents me from selling non-GPL Boxi licenses if I so desire. It uses 
Cygwin libc emulation which has different semantics to MSCVRT, so things 
that work directly won't work through OpenSSL/cppunit/etc and vice versa. 
The presence of two implementations of libc functions such as mkdir(), 
stat(), etc. may lead to the wrong one being used, and therefore 
application crashes. Cygwin applications use fake unix paths like /usr and 
/cygdrive/c which make no sense to Windows users or applications, and 
cygwin openssl will too, so loading a certificate won't work as we supply 
a windows path to a cygwin dll.

Cheers, Chris.
