Subject: [Boost-build] Boost.jam and 32 vs. 64 bit compilations
From: Anthony Foglia (AFoglia_at_[hidden])

        We primarily compile in 64 bit, but sometimes need 32 bit compilations.
  We used to have custom-made rules for the boost libraries, but I'm
working on switching to using the boost.jam distributed in contrib.

        Is there a way to configure the rules in there so the library search
path correctly finds either the 32- or 64-bit libraries as needed.

        I tried lines like :

using boost
    : 1.38
    : <include>boost_1_38_0/include/boost-1_38

But the conditional parameter logic confuses boost.jam into thinking
boost isn't configured.

        I tried looking at the functions in property and property-set, but
couldn't find anything to evaluate the rules to collapse the library
property to just one. I'm guessing it's not even possible, because the
address-model feature prints as "16 32 64" even though I'm explicitly
passing in on the command-line.

        Is there some other simple way to add this ability?
