nvm.lua-2.0 in Cygwin

I've hit a bug in compiling nvm.lua-2.0 in Cygwin, while running 'make
check';

/usr/include/boost/math/special_functions/detail/lgamma_small.hpp:483:38: error: expected primary-expression before 'do'

It's the L macro, due to Boost 1.48 (which Cygwin has). 

It's also mtn issue 191. That gives a patch; has that been committed
yet? I don't see it in the commit log.

It's a very small change; for now, I'll apply it on the nvm.lua-5.2
workspace, but not commit it.
