This one is less stable your previous change + reversion of tausq's
SMP TLB opimization patch.  GCC build doesn't get far before wierdness
occurs (strange characters being read from files):

gcc -c -g -fkeep-inline-functions      -gnatpg -gnata -I- -I. -Iada -I../../gcc/
gcc/ada ../../gcc/gcc/ada/exp_ch6.adb -o ada/exp_ch6.o
