How do you get that?  check_stdout prints "write error" if either there
was an I/O error on a previous write (in which case it is too late
to know what sort of error it was) or if fclose fails.  You couldn't
know that fclose failed with "invalid file handle" just looking at the
source.

Victor Griswold posted here about the work he did on RCS and CVS to
get them to work properly with cygwin, at least with binary files;
I don't recall whether he encountered other problems.  You might
check the archives.
