Sorry for the confusion.  I meant "native to cygwin".  i.e. I'm /not/
using -mno-cygwin, and I'm getting libraries built against the cygwin
DLL.  These are installed as libfoo.la -> /bin/cygfoo.dll.

Currently just the win32 backend.  I will build an X11 version in due
course.

Yes, though I may try (2) in the future if it has any benefits for me.
