Building xen.rpm in SLES11 started to fail due to these compiler warnings: [ 1436s] ../grub-upstream/netboot/fsys_tftp.c:213: warning: operation on 'block' may be undefined [ 1437s] ../grub-upstream/netboot/main.c:444: warning: operation on 'block' may be undefined [ 1234s] E: xen sequence-point ../grub-upstream/netboot/fsys_tftp.c:213 [ 1234s] E: xen sequence-point ../grub-upstream/netboot/main.c:444 The reason for this is that the assignment is done twice: tp.u.ack.block = ((uint16_t)( (((uint16_t)((block = prevblock)) & (uint16_t)0x00ffU) << 8) | (((uint16_t)((block = prevblock)) & (uint16_t)0xff00U) >> 8))); Fix this package build error by adding another patch for grub, which moves the assignment out of the macro usage.
