Sorry, I forgot to answer the rest of your questions in the hurry:

uname -a:
CYGWIN_NT-6.1-WOW64 F1S712WWS 1.7.30(0.272/5/3) 2014-05-23 10:36 i686 Cygwin
$ ldd `which df`

        cygintl-8.dll => /usr/bin/cygintl-8.dll (0x6f7c0000)

Debugging sessions would of course be okay on a test machine.

I'm not quite sure if I installed cygwin in 32bit or 64bit flavour but I am
actually upgrading packages with setup-x86.exe for some months now..
