As Andrew points out, NTFS can be case-sensitive as well, and on Windows
the case-sensitivity vs. case-preserving behaviour can be chosen for
each file or directory descriptor at the time the file is opened.
IMHO it's actually a pity that the filename comparison behaves differently
on different systems. I think it would make sense to behave identical on
all systems. What about this: Always search case-sensitive. If file has
been found, return. Otherwise, search case-insensitive.
Talking about case-insensitive comparison, the filename_cmp and
filename_ncmp functions don't work for multibyte codesets, only for
singlebyte codesets. Given that UTF-8 is standard nowadays, shouldn't
these functions be replaced with multibyte-aware versions? Along the
same lines, the entire set of safe-ctype functions only work for ASCII
and EBCDIC...
