Cygwin's binutils could link to DLLs (shared libraries) from the 
beginning, if only because Windows' own APIs are all DLL-based.

I did a fair bit of Googling to try and find out when gcc -shared 
started working, but couldn't find a reference.  I'd guess it was pretty 
early on, since I can't remember a time when Cygwin couldn't create 
DLLs.  (I've been using Cygwin since B18, the first packaged release.)

There have been occasional problems.  For instance, I seem to recall a 
problem where C++ library DLLs failed when thrown exceptions crossed the 
DLL boundary, many years ago.  While that problem existed, the standard 
recommendation was to build affected libraries statically, since they 
wouldn't work right otherwise.  But, that's very much not the same thing 
as "Cygwin cannot create DLLs."
