You can add this to the user-config.jam:

modules.poke : ARGV : [ modules.peek : ARGV ] --abbreviate-paths ;

--md5 (i.e. --hash) makes boost build create intermediate dirs with name 
of constant size (32). For example, you get something like

bin\2ffa9142d260c9eeb431ecbd2fbd244c\

instead of

bin\runtime-link-static\threading-multi\...\

So it should help if your intermediate paths are expected to be longer
than 32 characters.
