I wasn't sure which package you were talking about.  i reinstalled both cygwin and base-cygwin.

base-cygwin is 3.8-1
cygwin is 3.1.6-1

no difference.

yes, libiconv2-1.14-3, is what i see also

i really, really need to re-install cygwin from scratch on this machine.  it seems that every problem i see cannot be replicated.  

While trying to debug my "graphics characters don't appear correctly" issue, i did try to set-up a new install directory and use that, but maybe that's not good enough.

Can I just back up my home directory, kill the entire cygwin64 directory and start over ?
