 Things are not so obvious as you think.

 It's a bad design, when linker automatically sets it, but doesn't allow to
 pass it.

 > tor-for-Windows build chain
 Firefox's chain, Tor Browser's chain, TBB's (incl. Expert?) chain, and
 then that. First chain has it, second - inherits, third - only for
 Firefox, fourth - not a TBB Team's problem? And this ticket doesn't
 improve TBB then.
 Somebody should synchronize 'em all.
