extra error from gcc-2.3.1 tests

Good evening all.

This is an extract from the test results from my gcc-3.3.1 compilation in 
chapter 6 of LFS-5pre3 on i686-pc-linux-gnu. The rest was identical to the 
results posted by Greg Schafer as linked in the book (besides the f77 and 
objc bits which showed no failures at all).

Running target unix
FAIL: gcc.c-torture/unsorted/set386.c,  -O0
FAIL: gcc.dg/duff-2.c (test for excess errors)
FAIL: gcc.dg/uninit-C.c (test for excess errors)

The failed gcc.c-torture/unsorted/set386.c, -O0 wasn't there after pass2 of 
chapter 5. Do I need to worry? Since I never really compile with -O0 I'd like 
to ignore this, on the other hand ... the test in question caused a kernel 
oops pasted below.

For the rest I followed the instructions to the letter I hope (besides having 
a need for a fortran compiler - I added objc because it seemed small enough 
and it seemed like a good idea at the time)
