Hi,

I've forgot about one error I noticed last night.

When I'm trying to build projections.cpp test program using GCC, I'm
getting error message(s) about undeclared _hypot:

gcc.compile.c++ bin/projections.test/gcc-4.3.3/debug/projections.o
In file included from ../../../boost/ggl/projections/factory.hpp:46,
                 from projections/projections.cpp:17:

Cartesian, Parameters>, LatLong, Cartesian, Parameters>::LL_T&, typename

Cartesian, Parameters>, LatLong, Cartesian, Parameters>::XY_T&) const?:
../../../boost/ggl/projections/proj/geos.hpp:92: error: there are no
arguments to ?_hypot? that depend on a template parameter, so a
declaration of ?_hypot? must be available

It looks like it was introduced during recent update to the proj stuff
generator.

Best regards,
