The change was reverted several weeks ago:

I'm not quite sure what you're talking about here because there is no
such thing in unix as an exit value greater than 255.  After the
2005-03-08 revert (and prior to 1.5.13) you will never see an errorlevel
outside of the range 0-255 for a cygwin application that was called from
a windows app.
