1528,g++ 4.3.0 reports error because of redeclaration of next,jensseidel@…,Aleksey Gurtovoy,"Compiling parts of Fusion shows the following bug in MPL with a recent g++ 4.3 snapshot:

I think the problem is that in boost::mpl::zip_iterator
boost::mpl::next is visible and does not allow to define
a new next (even if relative to zip_iterator).

See http://en.opensuse.org/GCC_4.3_Transition and http://gcc.gnu.org/ml/gcc/2007-09/msg00480.html for more details.

Just renaming one of the ""next"" fixes this problem but introduces of course many more.

PS: Please fix the typo ""shorcuts"" in one of the MPL header file.",Bugs,closed,Boost 1.36.0,mpl,Boost Development Trunk,Problem,fixed,,
