[gopher] GopherVR running on Cygwin

[RichardG .]

Working on all its glory: http://i.imgur.com/I4XW8os.png

Only two steps to make it compile with make linux:
- Extend the OS X special case to __CYGWIN__ in gopher/object/Regex.h
because NTFS is *also* case insensitive.
- Remove OS X specific cflags in gophervr/Makefile

Here's the binary: https://dl.dropbox.com/u/861751/Gopher/gophervr-cygwin.zip
Should only need X11 and motif (it's available as a package) to run.
Building on the other hand, I haven't tracked down what do you need to
build it, but I had to install libXt-devel and libXm-devel.
