Beats the heck out of me.  I didn't have Cygwin installed.  I ran the installer.  It hung at this point.  I eventually cancelled it, because it obviously wasn't going to complete.  This output is from one of the later retries.  I never attempted to run anything installed in cygwin, I'm just trying to complete the installation.

More weirdness.  I ran a mintty window, and I ran those command lines, but it gives me lots of lines like this:
-------------
2 [main] bash 28452 child_info_fork::abort: C:\cygwin\bin\cygiconv-2.dll: Loaded to different address: parent(0x4D0000) != child(0x2E0000)
bash: fork: retry: No child processes
-------------

I don't believe either of these command lines did anything, but just to be sure, after I ran them I killed the window an reran setup, and got the same symptoms.
