OK, I've got it working on Xubuntu (still no joy in cygwin).

I can confirm that it works in 1.55 but is broken in 1.56.  Also that 
the breakage is somewhere in the MPL headers.

I've tried reverting one change at a time (see 
https://github.com/boostorg/mpl/compare/boost-1.55.0...boost-1.56.0), 
but for some reason still couldn't narrow it down.  Anyone any ideas?
