Copying non-tried blocks... Pass 1 (forwards)
ddrescue: /dev/sde1: Fatal error reading the input file: No such device 
(errno=19)


The Cygwin DLL 3.5.1 now maps ERROR_MEDIA_CHANGED to ENODEV. EACCES is 
still the default for "other" codes, but this never occured for read 
errors in my testcases.

See also new Cygwin behavior above.

BTW, the Makefile problem is also fixed.
