1914	Boost.PropertyTree JSON parser in SVN trunk does not compile with Spirit2 changes	ramon.casellas@…	kaalus	"Boost.PropertyTree JSON parser in SVN trunk does not compile with Spirit2 changes.

See g++ 4.1 log.

Attached patch that solves the issue (at least for me). A hack, surely there exists a better/cleaner patch

(compile)
