This is a probably an issue related to the use of POSIX-style line endings. 
Try the eCos Configuration Tool which shipped with eCos 2.0 - it should set 
up the Cygwin mount table correctly to use a text-mode mount point with 
recent Cygwin. You will need to delete the old mount point using
"umount /ecos-c" before you switch.
