State of maturity for gcc 2.95.3 and gcc 2.96

[David Edelsohn]

	Currently the error occurs in a large fragment of code and I am
having trouble creating a small, self-contained testcase.  Basically, when
I tried to extend the unsigned immediate operand fix to another pattern
which had been missed, I received the following error on the gcc-2.95
branch:

../xlate4.c: In function `SegTabFindMapping':
../xlate4.c:77: internal error--unrecognizable insn:
(insn 407 406 296 (set (reg:DI 10 r10)
        (mem/u:DI (symbol_ref/u:DI ("*LC..4")) 0)) -1 (nil)
    (nil))

This is GCC operating in 64-bit PowerPC mode, so you will not see it on
your Linux builds.
