The guidelines for reporting Cygwin problems are outlined in
<>.  It would have helped if you had
attached (as an uncompressed text *attachment*) the output of "cygcheck

At a guess, you either have an older cygwin1.dll (i.e., you had a Cygwin
process running while upgrading), or you have more than one copy of
cygwin1.dll on your system.  The cygcheck output requested above will
confirm or deny these guesses.  If the former is correct, you should get
things working after a reboot.  If the latter, simply delete the extra
(older) copies of cygwin1.dll, leaving only the one in /bin.  Be aware
that the other copies of cygwin1.dll may not be in the Cygwin tree.
