GCC ≥ 4.8 warns about unused local typedefs

[the-nic]

Using gcc ≥ 4.8 causes a lot of warnings about unused local typedefs to be emitted, eg. (there may be more):

include/boost/numeric/ublas/triangular.hpp:1862:46: warning: typedef ‘difference_type’ locally defined but not used [-Wunused-local-typedefs]
include/boost/numeric/ublas/detail/matrix_assign.hpp:969:40: warning: typedef ‘value_type’ locally defined but not used [-Wunused-local-typedefs]
include/boost/numeric/ublas/detail/matrix_assign.hpp:1280:39: warning: typedef ‘size_type’ locally defined but not used [-Wunused-local-typedefs]

..and so on. This causes a lot of noise in compiler output

Many of those have been dealt with but cannot be all catched by the unit tests. If after release 1.57 some of them still remain please repost them so we can get rid of them.

Thanks!

Hereafter, two warnings which have remained (MinGW gcc 4.9.1):

boost_1_57_0/include/boost/numeric/ublas/detail/matrix_assign.hpp:1262:39: warning: typedef 'size_type' locally defined but not used [-Wunused-local-typedefs]
boost_1_57_0/include/boost/numeric/ublas/detail/matrix_assign.hpp:1288:39: warning: typedef 'size_type' locally defined but not used [-Wunused-local-typedefs]

Kind Regards,

Thanks for reporting!

This shouldn't be a problem because the typedef is used right below but gcc has a different opinion. Anyway to avoid it I pushed a fix in the develop branch.
