Subject: ntfs: fix POSIX vs Win32 filename compares
X-Git-Tag: syslinux-4.06-pre2~12

ntfs: fix POSIX vs Win32 filename compares

When using the COMBOOT32 module "ls" for listining directory entries on
an NTFS volume, for e.g. directories as "/Foobar" (a Win32 filename)
could be only listed as "ls.c32 /foobar" and neither "ls.c32
"/Foobar" nor "ls.c32 /FOOBAR". POSIX filenames must be handled in a
case-sensitivity way, while Win32 filenames are handled in a
non-case-sensitivity way.

Note also that the POSIX/Win32 filename compare is done in the
ntfs_filename_cmp() function.
