Replying to [comment:14 leif]:
> An IMHO better solution is to also add `-march=native` to `CFLAGS`,
since this enables SSE (to be precise, allows SSE2 instructions) if
supported by the processor (when `configure` defines `HAVE_SSE2`),
ignoring `SAGE_FAT_BINARY` at least for the moment (unless ECM's
`configure` has an option like `--disable-sse` or similar; I haven't
really checked that yet, perhaps just `--enable-sse2=no` on ''32-bit''
x86).
You know that -march=native is only supported on x86 and amd64 cpus right?
I can tell you first hand that the compilation will stop straight away on
ppc.
And then you will get Dave telling you it is not supported by other
compilers.
