Check your mount types under cygwin.
if you type mount under cygwin it will say if the drives are mounted in text or binary
The mount type of the drive where the source resides is important. AFAICR the mount type should
be text for the source. I have had extermely strange error messages and problems when the mount
type under cygwin was incorrect. #defines with the \ line continiation character does not compile. Standard
header files are not found etc.
Hope this helps
