+  The following two compiler directives are specific to the Microsoft Visual
+  C++ family of compilers
+
+  Fundementally what they do is instruct the linker to use these two libraries
+  for the resolution of symbols. In essence, this is the equivalent of adding
+  these two libraries to either the Makefile or project file.
+
+  This is NOT a recommended technique, and certainly is unlikely to be used
+  anywhere else in wxWidgets given it is so specific to not only wxMSW, but
+  also the VC compiler. However, in the case of opengl support, it's an
+  applicable technique as opengl is optional in setup.h This code (wrapped by
+  wxUSE_GLCANVAS), now allows opengl support to be added purely by modifying
+  setup.h rather than by having to modify either the project or DSP fle.
+
+  See MSDN for further information on the exact usage of these commands.
