29 You should be specifying '-march=athlon64'.
30
31 '-athlon64' is not a valid CFLAG, also -sse/2 and -3dnow are all implied
32 by -march=athlon64 and I'm quite sure that -mfpmath=sse is also the default
33 on amd64. It may be useful to specify '-msse3' in the CFLAGS though if your
34 cpu supports SSE3 as no -march setting implies it yet. Although it's unlikely
35 that gcc utilises sse3 properly.
36
37 I recommend the following CFLAGS:
38
39 CFLAGS="-O2 -march=athlon64 -pipe"
40
41 Adding -msse3 if appropriate for your cpu.
