Using GL commands in vga.c to add VGA bitplane support

[Jeremiah Flerchinger]

I want to use wGL in VGA.c to add bitplane support and other 
functionality.  What would be the correct or "preferred" method of 
implementing this?  As it stands I am looking at something like the 
following to bring in GL functions:

  #include <GL/gl.h>
  typedef void (WINAPI *glClearColorProc)(float,float,float,float);
  static glClearColorProc ptr_glClearColor;
  HMODULE wgl_Lib = LoadLibraryA("opengl32.dll");
  if (wgl_Lib)
  {
    ptr_glClearColor = GetProcAddress(wgl_Lib, "glClearColor");
  }

Is this the preferred way to make use of openGL inside of Wine?  Is 
there a better way?  I really don't want to have to figure out a typedef 
and make a pointer for every single library function I plan to use. Plus 
I find it annoying I can't use the real name of the function and am 
stuck using a differently named pointer.

Thanks in advance,
