There are no occurrences of the word "macro" anywhere in gl.ffi.  I 
think ffigen skipped over all the #defines.  The first bit of the file 
looks like this:

(type ("/System/Library/Frameworks/OpenGL.framework/Headers/gl.h" 40)
  "GLenum"
  (unsigned-long ()))
(type ("/System/Library/Frameworks/OpenGL.framework/Headers/gl.h" 41)
  "GLboolean"
  (unsigned-char ()))
(type ("/System/Library/Frameworks/OpenGL.framework/Headers/gl.h" 42)
  "GLbitfield"
  (unsigned-long ()))
(type ("/System/Library/Frameworks/OpenGL.framework/Headers/gl.h" 43)
  "GLbyte"
  (signed-char ()))
(type ("/System/Library/Frameworks/OpenGL.framework/Headers/gl.h" 44)
  "GLshort"
  (short ()))
(type ("/System/Library/Frameworks/OpenGL.framework/Headers/gl.h" 45)
  "GLint"
  (long ()))
(type ("/System/Library/Frameworks/OpenGL.framework/Headers/gl.h" 46)
  "GLsizei"
  (long ()))
(type ("/System/Library/Frameworks/OpenGL.framework/Headers/gl.h" 47)
  "GLubyte"
  (unsigned-char ()))
(type ("/System/Library/Frameworks/OpenGL.framework/Headers/gl.h" 48)
  "GLushort"
  (unsigned-short ()))
(type ("/System/Library/Frameworks/OpenGL.framework/Headers/gl.h" 49)
  "GLuint"
  (unsigned-long ()))
(type ("/System/Library/Frameworks/OpenGL.framework/Headers/gl.h" 50)
  "GLfloat"
  (float ()))
(type ("/System/Library/Frameworks/OpenGL.framework/Headers/gl.h" 51)
  "GLclampf"
  (float ()))
(type ("/System/Library/Frameworks/OpenGL.framework/Headers/gl.h" 52)
  "GLdouble"
  (double ()))
(type ("/System/Library/Frameworks/OpenGL.framework/Headers/gl.h" 53)
  "GLclampd"
  (double ()))
(type ("/System/Library/Frameworks/OpenGL.framework/Headers/gl.h" 54)
  "GLvoid"
  (void ()))
(function ("/System/Library/Frameworks/OpenGL.framework/Headers/gl.h" 
2104)
  "glAccum"
  (function
   ((typedef "GLenum") (typedef "GLfloat") )
   (void ())) (extern))
(function ("/System/Library/Frameworks/OpenGL.framework/Headers/gl.h" 
2105)
  "glAlphaFunc"
  (function
   ((typedef "GLenum") (typedef "GLclampf") )
   (void ())) (extern))
(function ("/System/Library/Frameworks/OpenGL.framework/Headers/gl.h" 
2106)
  "glAreTexturesResident"
  (function
   ((typedef "GLsizei") (pointer (unsigned-long ())) (pointer (typedef 
"GLboolean
")) )

And so on.  Note the jump in line numbers.
