That is wrong, feel free to change it to a better default.

That is a general problem with cygwin interacting with non-cygwin 
programs. Cygwin invents its own virtual filesystem that is not 
understood outside of cygwin. See the problems the native build of Emacs 
faces with Cygwin make. I don't see how bypassing browse-url fixes this 
for you, as the path will still be one that Windows does not recognize.
