+dumapp: fix for C++14
+
+With C++14, the way exceptions are specified has changed (somehow, don't
+ask me), thus causing build failures:
+
+    dumapp.cpp: In function ‘void* operator new(std::size_t)’:
+    dumapp.cpp:192:19: error: declaration of ‘void* operator new(std::size_t) throw (std::bad_alloc)’ has a different exception specifier
+     void * DUMA_CDECL operator new( DUMA_SIZE_T size )
+                       ^~~~~~~~
+    In file included from dumapp.cpp:39:0:
+    dumapp.h:91:23: note: from previous declaration ‘void* operator new(std::size_t)’
+     void * DUMA_CDECL operator new(DUMA_SIZE_T) throw(std::bad_alloc);
+                       ^~~~~~~~
+
+This is most evident with gcc-6.x, since the default C++ standard has
+changed from C++11 to C++14, thus exposing these new failures.
+
+Fix that by guarding the exception handling, a bit like was done
+with GRASS GIS (thanks DuckDuckGo):

+I doubt it is still active, so the patch was not sent upstream. :-/
