This won't help when b2 is itself called from within a too long path. 
The Jenkins matrix project plugin is especially bad for this.

To workaround that problem, have Jenkins create a junction point 
close to the root using mklink /j. Change directory into the junction 
point, and work from there.

The only big downside to that technique is you must serialise jobs on 
Windows slaves, because two jobs will try to set the same junction 
point and it races. I solve that by dropping the executors to 1, and 
firing up more than one Windows slave VM. Kernel memory sharing 
reduces the RAM cost of this very considerably, so it's not a 
terrible workaround.
