interix-wgcc is exactly for that purpose.

wgcc implements gcc interface, but beneath it uses cl.exe to compile and
link.exe for linking. Though with wgcc you get native win32 libs and
executables.

For building an opensource package you only to overwrite CC, CXX and LD
to use wgcc instead of gcc.

With wgcc such stunts aren't necessary, because if you've build your
package with wgcc you've got native win32 libs.
Maybe you have to port some things in you opensource package though wgcc
can compile the source.
