   7 #   If you are using gcc-2.7.2.3 or earlier:
   8 #   The optimizer of gcc has a bug and in general you should not specify
   9 #   -funroll-loops together with -O (or -O2, -O3, etc.)
  10 #   This bug is supposed to be fixed with release 2.8 of gcc.
  11 #
  12 #   This bug does NOT seem to have an effect on the correct compilation
  13 #   of this benchmark suite on my Linux box. However, it leads to
  14 #   the dreaded "internal compiler error" message on our alpha
  15 #   running DEC Unix 4.0b. The Linux-binary that was used to obtain
  16 #   the baseline results was nevertheless compiled with
  17 #   CFLAGS = -s -static -Wall -O3 -fomit-frame-pointer -funroll-loops
  18 #
  19 # You should leave -static in the CFLAGS so that your sysinfo can be
  20 # compiled into the executable.
