I always have trouble remembering how Cygwin tools work...

After investigating, the answer seems to be: specify the ".dll" files
in the command line above, not the ".lib"s. That worked for me with
v299 and MSVC-built DLLs, at least.

When you build v299.x from scratch using gcc, you get a Unix-style
build, so the libraries should be in plt/lib, not plt/lib/gcc. For
v299.x, files in plt/lib/gcc are meant to support gcc-compiled
extensions for a Windows-style build.

The story was different for v209, where using gcc produced a
Windows-style build --- but there were lots of problems with that
