[Rd] Building package under windows which links against a cygwin library

[Cameron Bracken]

I am developing a package
(http://r-forge.r-project.org/projects/swfdevice/) which links against
the ming C library. The package builds fine under Mac OS X and Linux.
I am really out of my element on windows, but I know there is a cygwin
package for libming.

My question is, does anyone have advice/examples on linking R packages
against cygwin libraries?  Is this even possible?  How would I go
about writing a configure.win script to do this?

Cheers,
