I'm not so sure about this.   Question: is it possible to write GPL'd
software under Windows that links into, say, USER32.DLL?  Answer: yes,
because USER32.DLL is considered part of the operating system.
It might be that cryptoapi's dll is also considered part of the win32 
operating system api, thus allowing even gpl'd apps to dynamically 
link to it without violating the gpl.
