This is dead WRONG, and so it was a couple of weeks ago when someone told
the same thing.

The -2 calls (like DosOpen2) are NOT for HPFS support, but for Extended
Attribute linking.  The "old" API's fully support the HPFS long filenames,
and the only thing you have to do is to use the DosOpen call and set the
NEWFILES flag in your EXE-header.

If you use a C-function for opening a file (like fopen), this should also
be OK with HPFS long filenames, but you have to check that the library
reserves enough space for your filename.
