I suppose a reasonable substitute for detecting files with the same
(case-folded) name might be somethign along these lines:-

find "$@" \( -name "* *" -o -name "*
*" \) -printf "[%p] contains a newline or a space and so is not legal in DOS\n" 
>&2

find "$@" \! -name "* *" \! -name "* 
*" -print | sort -fu | uniq -in | awk '$1 > 1 {printf("%d files have a name 
like %s\n", $1, $2);}' >&2


I agree that it would be interesting for pathchk to be able to do this
sort of thing.  Perhaps for case-folded filenames, the check would
need to be made once with LC_COLLATE=POSIX and once with the local
collation order (because the files may be named in a non-English
alphabet).
