-# OBSOLETE MACRO
-#
-#   This macro is no longer maintained here; the author prefers to publish
-#   it at <http://code.google.com/p/autoconf-gl-macros/>.
-#
-# SYNOPSIS
-#
-#   AX_CHECK_GLU
-#
-# DESCRIPTION
-#
-#   Check for GLU. If GLU is found, the required preprocessor and linker
-#   flags are included in the output variables "GLU_CFLAGS" and "GLU_LIBS",
-#   respectively. If no GLU implementation is found, "no_glu" is set to
-#   "yes".
-#
-#   If the header "GL/glu.h" is found, "HAVE_GL_GLU_H" is defined. If the
-#   header "OpenGL/glu.h" is found, HAVE_OPENGL_GLU_H is defined. These
-#   preprocessor definitions may not be mutually exclusive.
-#
-#   Some implementations (in particular, some versions of Mac OS X) are
-#   known to treat the GLU tesselator callback function type as "GLvoid
-#   (*)(...)" rather than the standard "GLvoid (*)()". If the former
-#   condition is detected, this macro defines "HAVE_VARARGS_GLU_TESSCB".
