$ cygcheck -cd cygwin

will give what you want *PROVIDED* cygcheck itself is working *AND* that
you have not replaced the cygwin DLL with a snapshot version.

Corinna is trying to give a foolproof way of determining EXACTLY the
version of the *dll* that you have installed, even if almost everything
is broken, right down to the exact time she compiled it on her system.
You can't get much more exact than that.

You can do this in a cmd box, without bash:

> cd C:\cygwin-1.7\bin\
> uname -a

and it really only involves a single system call to the cygwin DLL's
uname() function, plus some stdio. (Okay, there's some libintl stuff
going on too, but if you don't set LC_*, then that's mostly inactive).
So it'll work even if, for whatever reason, your cygwin is almost
totally borked.
