The location of the boost install is solved by specifying Boost_DIR (or
BOOST_DIR?) as an environment variable (using FindBoost module)
It's indeed the directory of binaries inside that install location which is
found automatically by the module only for one architecture.

I agree it would make things straightforward.
The changes necessary would just be to set these as default directories for
output binaries into b2 (on windows only?) and the windows installer I
Then a patch to the FindBoost module can finally happen.
