You're apparently quoting an old message with no attribution and
providing no way of knowing whether this relates to an already fixed bug
or not.

I think you're a tad confused.  This is cygwin, not zeusedit.  Cygwin's
make doesn't even contain the string "DuplicateHandle(ln)".

And, for once, it looks like zeusedit doesn't actually use cygwin at
all.  I'm probably wrong and they are the standard people abusing the
cygwin license in the standard way, but AFAICT, they seem to be
using a windows version of make.
