Missing __THROW on hypot extern definition in vtklibproj4
Using g++ 5.4.0 on CentOs 7.3.1611 (Core), I'm unable to compile VTK-8.0.0 as Line 85 of VTK-8.0.0/ThirdParty/libproj4/vtklibproj4/src/projects.h has an extern for hypot that does not match what is in mathcalls.h. Specifically, mathcalls.h declares hypot as throw() whereas vtklibproj4 extern does not. Therefore Line 84 needs to be changed from
extern double hypot(double, double);
to
extern double hypot(double, double) __THROW;
