Here's the synopsis:
Been trying to compile LFS (from the latest svn version) on my laptop, I have
tried four times so far (please note I'm making use of JHLAFS). During all
the
four builds, gcc tests don't seem to be satisfactory as the number of
unexpected
failures is too high and the number of expected passes is too low. I have tried
changing the CFLAGS and tried to be conservative but, the result seems to be
the
same. The fourth time I chose to run tests both for the tools and the final
system. As I can see tests for all other packages are successful (All # tests
were successful) except for gcc ! The CFLAGS I used for the fourth build are
"-O3 -pipe -msse -msse2 -mmmx -march=native -mtune=native". The processor is an
Intel Penitum4 Mobile.
The only deviations from the SVN book are m4 (using 1.4.16), mpc (using 0.9),
less (using 446).
Here's the "grep -A7 Summ" output:

I can't figure out what am I doing wrong here.
