Currently compiling the tap sources breaks on Mac OS X. This is because of: 1) tap-linux.h requiring Linux includes 2) typos 3) missing #includes This patch adds what's necessary to compile tap happily on Mac OS X. I haven't tested if using tap actually works, but I don't think that's a major issue as that code was probably seriously untested before already. I didn't split the patch, because it's only a few lines of code and splitting is probably not worth the effort here.
