    Well that is weird.  I just tried it on my Win7 and it works
as expected. 

    What directory are you running it in?  Could permissions be involved?

    Also what window are you running in?  I doubt it should be the case, but
some windows programs won't generate output in a cygwin shell or a
cygwin tty,
but will in cmd.e

    Have you tried running with 'strace' to see what calls it executes?:

strace -f ./hello
