ERRORLEVEL is a variable that is set and maintained by cmd.exe. The Cygwin
(actually bash) equivalent would be the variable $?, e.g.,

some_command param1 param2 ...
if [ $? != 0]
then
  # The command failed
fi

There are a number of possible variations on this syntax. The equivalent exists
for csh/tcsh, but I don't use any of the csh-like shells, so I don't know the
syntax off the top of my head.
