It will show me my private project files in a rigth manner but the eCos files will not be showed. The problem is that the debugger will not found the files because the path is prefixed with "/ecos-c/...". T32 is a Win32 application and can not expand such text to a drive letter. Therefore I am not able to step through the eCos code.

Sorry about my first short answer.

My first idea was to make the cygwin path match the windows patch with
exception of the drive letter. A lot of windows apps are resistant to
both separators. I don't know if T32 is, but it might. GCC will store
the path given by ecosconfig anyway, and ecosconfig does not even let
us make a single try.
