[M3devel] 386?486?586?686?etc.?

There was a recent thread on the gcc lists about this.

Fedora 11 requires Pentium ("586").

Fedora 12 requires Pentium Pro ("686").

Various distros also use xz/lzma instead of gzip.

  But OpenBSD sticks with gzip for perf on old machines.

  Our .deb files use lzma, if the machine building them has the tools.

Wow. What for? And with Modula-3? What OS?
I think Pentium will be ok.
I think ultimately, if people really need, we should have separate targets.
As I've been saying, like: I386_FREEBSD_USERTHREADS, I586_FREEBSD, etc.
 Esp. to enable easier "release engineering", such as when we do more cross builds,
  adding new targets will be cheaper. But we'd want some sort of system
  where if nobody downloads and installs and minimally tests a release, it is
  in some low grade classification.
  Certain ones we'd test automatically, like whatever we have available in Hudson.
