No, the bug is present in all released versions of gcc. They need
to build a snapshot from the current GCC svn tree (4.3, 4.4 or trunk),
or apply the patch to their own source.

* pa.c (compute_zdepwi_operands): Limit deposit length to 32 - lsb.
Cast "1" to unsigned HOST_WIDE_INT.
(compute_zdepdi_operands): Limit maximum length to 64 bits. Limit
deposit length to the maximum length - lsb. Extend length if
HOST_BITS_PER_WIDE_INT is 32.
