------- Comment #3 from pinskia at gcc dot gnu dot org 2008-09-14 04:59 -------
Confirmed, you can also get rid of the struct:
void _posix_to_nfsv4_one (unsigned *ace, short deny, int flags)
{
int eflag = (flags ? (0x00000001 | 0x00000008) : 0);
if (deny)
*ace= eflag;
*ace= eflag;
while (*ace)
*ace= eflag | 0x00000040;
}
