#
#  Pentium:  -DSINGLE_PIPE	 make processor use only one pipe
#  Pentium:  -DNO_LARGE_PAGES	 do not use Pentium large page optimizations
#  Pentium:  -DNO_GLOBAL_PAGES	 do not use P-II/PPro global page optimizations
#  Pentium:  -DALLOW_USER_RDTSC	 permit RDTSR instruction from user level
#  Any:      -DWRITE_THROUGH	 make all pages write-through
#  Any:      -DSTRESS_TEST       runs things in ways designed to break things

# Some legacy compilation options:
#  -DSUPPORT_386    support obsolete processors
