[sigc] missing file for msvs builds

[Garrett McGrath <gmcgrath815 gmail com>]

I recently downloaded the latest version of libsigc++ and attempted to 
build it to fill a dependency requirement in another software package 
I'm trying to get built.  Every time I attempt to build the latest 
version (2.0.18) it fails looking for the file resource.h, I have 
checked previous versions and seem to be unable to locate the file in 
those versions as well.  The older versions seem to fail compilation as 
well for a variety of different files missing from where it's looking 
for them (and from the distribution entirely).  any help would be wonderful.
