dnl # 3.3 API change
dnl # The VFS .create, .mkdir and .mknod callbacks were updated to take a
dnl # umode_t type rather than an int.  The expectation is that any backport
dnl # would also change all three prototypes.  However, if it turns out that
dnl # some distribution doesn't backport the whole thing this could be
dnl # broken apart in to three seperate checks.
