that's wrong.
the declaration of open64 is:
> int open64(const char *pathname, int oflag,...);
so it returns an int, not an off_t, just like open_via_file().

iiuc, the problem is, that the file descriptor cannot be used by an
ordinary lseek(), but only with lseek64().

that's what i was referring to when i said that one would need to
provide sys_lseek().

if you go the way of simply defining _FILE_OFFSET_BITS=64 for
compiling Pd, you must compile all externals using
_FILE_OFFSET_BITS=64 as well, else they won't be able to the
file-handle internally.
i think this is **very** bad style, as it forces the use of some
obscure and potentially harmful compiler flags in order get externals
to work.
