hi guys.

i'd like permission to backport:

	http://gcc.gnu.org/ml/gcc-patches/2002-04/msg01546.html

to the 3.1 branch.  this will supercede my extract_bit_field
patch submitted yesterday.

i'd also like to commit the following testcase along with it (which
abort()s without the aforementioned patch).

ok for 3.1?
