Just figured it out...

regex correctly uses <sysinclude>$(BOOST_ROOT), for CW this is important
because it doesn't, by default search the user paths for system (<**>)

But signals is using <include>$(BOOST_ROOT), which is the user paths.

The fix is to change the signals Jamfile to use <sysinclude> instead.
