First option is:

project whatever
: requirements <os>SOLARIS:<cxxflags>"-m64 -mcpu=v9"
; 

You'd need to verify the spelling of 'SOLARIS' by creating file with

ECHO $(OS) ;

and running

bjam -f<the name of file>

Second option (that I've just introduced), is to put

using gcc : : : -m64 -mcpu=v9 ;

in site-config.jam on Solaris (you can drop the file to /etc so that you don't 
overwrite it when upgdading Boost.Build).

(BTW, Larry, this also solve your desire to add rpath elements, you can now 
really do:

using gcc : 3.4 : g++ : : -Wl,--rpath -Wl,whatever ;

A third option is to introduce <instruction-set> or <architecture> feature. We 
talked about it but nobody implemented that.
