Hmm... Well, I recall things such as:
C> copy con foo.txt
^Z
failing on MS-DOS. But it may be that it's not a problem in the FS,
but in copy. Anyway, automake uses `echo timestamp > file', instead
of touch, and I've always thought the reason was to avoid having an
empty file. OTOH, I've abused emoticons such as `: >' in the Samba
Makefiles, and I don't recall anybody having reported problems with
it. Maybe this is just portability myth...
I wouldn't mind having the testsuite failing in case an empty file
can't be created, but I'd be very concerned if autoconf or configure
scripts generated by it depended on this ability, for now.
