Boost-Build :

I've made a number of changes to my universal-binary supporting
darwin.jam patch (shipping with the Adobe Source Library) in order to
address the concerns raised by Rene and others at :

My current version supports invocations like:

  bjam architecture={combined,x86,power} link={shared,static}

That is, universal builds are now supported, along with 64 bit builds.
I'd like to ask for the help from a few volunteers who'd be willing to
test it out, before I submit my patch for consideration here. Anyone
interested in helping me test it?

One of the issues that remains pertains to folder naming. On the mac,
if a build doesn't specify an -arch parameter, the architecture (and
perhaps the address model) of the host machine is used. I'm not really
comfortable with the same folder path meaning different things on
different machines. So, I'd like to do something like the following in
darwin.jam (in invented pseudo code)

SWITCH(on result of /usr/bin/arch) { # host machine's architecture
   CASE(ppc) use <architecture>power/<address-mode>32 as the default
   CASE(i386) use <architecture>x86/<address-mode>32 as the default
   CASE(ppc64) use <architecture>power/<address-mode>64 as the default
   CASE(x86_64) use <architecture>x86/<address-mode>64 as the default
   DEFAULT error, unknown arch

Can someone guide me in towards the right way to express this in bbv2?
