Thanks for the info - nice to know that the cygwin version of ping is
getting better.
Not that it's going to make any difference to me & my scripts, but

$ which ping
/cygdrive/c/windows/system32/ping

$ ping www.examle.com

Pinging www.examle.com [69.172.201.208] with 32 bytes of data:
Request timed out.
Request timed out.
<crtl>C

$ echo $?
130

I've had a windows admin account for doing admin type things and a
user account with no special/extra privs for normal use ever since I
started using Win-XP, so the requirement to be running as admin (or
answer a UAC prompt) puts cygwin ping into the "does not meet my
needs" category.

My apologies.  If I offended you or anyone else it wasn't intentional.
I should have done a better job with my wording :(
