Comment (by fbissey):
Don't like the spkgs. Both SPKG.txt aren't updated to reflect the version
changes. The first thing that I see in both is
{{{
#!/usr/bin/env bash
CFLAGS="-fPIC -mtune=k8 -pedantic -std=gnu99"
LDFLAGS="-static"
}}}
-fPIC and -static are kind of opposite but you will want to fold a library
that you only know how to build static into a shared object so you need
the -fPIC. Would be better to build shared in the first place. Is the
"-mtune=k8" the thing that impose 64bitness? Anyway that assume way too
much about the underlying cpu even on x86_64. We have people working on
arm and ppc64, that's 64bit too.
When you say 64bit do you mean x86_64 as in "I have used simmd
instructions that are only available on this cpus"(pet hate) or something
else?
If you have used x86_64 specific instructions I am not sure we can ever
move this out of optional since we support (or at least aim to) a larger
range of hardware.
And just looking I have found assembly....
