+/*
+ 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 wxWindows 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.
