Good, and indeed, CLISP should probably not care either way about the mount
mode on which it writes these files, because that's the whole point of
textmounts: to provide a way for the user to instruct cygwin (the kernel,
effectively) to override the application's choice at a lower level when

Ok, that is simply the wrong default, and I think it is /that/ which needs
to be fixed.

Yes, it is really; unless CLISP used some compile-time autoconf test to
figure this out and adjust that default you mentioned, how else could it make

This smacks of a build/packaging error to me, but perhaps it was a
deliberate decision; we need to hear from the CLISP maintainer. Without
having looked into building CLISP, I don't know whether it would just need an
option when configuring or a #define patched into the source somewhere.
Can't think of a witty .sigline today....
