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

#	-fforce-addr -fforce-mem -falign-loops=2 -falign-functions=2 \
#	-falign-jumps=2 -funroll-loops

# for a newer gcc on a newer Pentium type processor you can try the following

#	-fforce-addr -fforce-mem -falign-loops=2 -falign-functions=2 \
