System.Posix.Signals

Hi, Why is System.Posix.Signals defined in base on Windows, but entirely blank, while System.Posix.Process is defined in Unix? If this is a dependancy issue, then shouldn't System.Posix.Internals.Signals be in the base, and then unix export System.Posix.Signals, which is just a reexport of this? This issue is annoying because I'm trying to at least write null stubs for the functions so I can compile a program requiring unix on Windows. It doesn't help that Windows ships a version of Signals with an entirely different interface... Thanks Neil
