2010-12-26  braden.mcdaniel

	* configure.ac: Update version to 20101226.
	* Makefile.am: Check to see if ChangeLog exists before removing it.

2010-12-25  braden.mcdaniel

	* m4/ax_check_gl.m4, m4/ax_pthread.m4: Remove dependency on
	  AX_PTHREAD; GL implementations do not need this. Also, remove
	  Nvidia-specific bits from AX_CHECK_GL: a correctly configured
	  Nvidia driver installation will not require this.
	* m4/ax_check_glut.m4: Increment AX_CHECK_GLUT version to 2.3.

2010-04-25  braden.mcdaniel

	* m4/ax_check_glut.m4: Rather than check for libglut with and
	  without -lXmu, just apply both -lXi and -lXmu if these libraries
	  are found on the system. We don't carry these flags into
	  GLUT_LIBS, so it really doesn't matter if they're unnecessary on
	  some systems.

2010-04-24  braden.mcdaniel

	* m4/ax_check_glut.m4: Kilgard's GLUT needs libXmu; but freeglut
	  does not. First check for -lglut without -lXmu.

2010-03-21  braden.mcdaniel

	* configure.ac: Update package version to 20100321; specify home
	  page in AC_INIT and require Autoconf 2.65.
	* m4/ax_check_gl.m4, m4/ax_check_glu.m4, m4/ax_check_glut.m4:
	  Update versions: AX_CHECK_GL to 2.6, AX_CHECK_GLU to 2.4, and
	  AX_CHECK_GLUT to 2.2.

2010-02-19  braden.mcdaniel

	* m4/ax_check_gl.m4: Don't add -L flag to GL_LIBS. Client code that
	  needs this should set it separately.

2010-02-18  braden.mcdaniel

	* m4/ax_check_gl.m4, m4/ax_check_glut.m4: Revert LIBS before
	  testing -framework flags.
	* m4/ax_check_gl.m4, m4/ax_check_glu.m4, m4/ax_check_glut.m4: Avoid
	  putting nonessential -l flags in the *_LIBS substitution
	  variables. These can lead to spurious dependencies. Clients that
	  need additional libraries now need to add them separately.
	  
	  Also, improve correctness of LIBS usage in tests; i.e., ensure -L
	  flags are put into LDFLAGS.
	* m4/ax_check_gl.m4: Avoid adding spurious -l flags to GL_LIBS.
	* m4/ax_check_gl.m4: Ensure that AX_CHECK_GL doesn't wind up
	  finding a libGL that links to X11 if no_x is "yes".

2010-01-25  braden.mcdaniel

	* configure.ac: Updated package version to 20100125.
	* m4/acx_pthread.m4, m4/ax_check_gl.m4, m4/ax_pthread.m4:
	  ACX_PTHREAD has been replaced with AX_PTHREAD in the Autoconf
	  Macro
	  Archive.
	* m4/ax_check_gl.m4, m4/ax_check_glu.m4: Windows platforms may need
	  to have included <windows.h> before OpenGL
	  headers are usable.
	  
	  Update AX_CHECK_GL version to 2.5.
	  
	  Update AX_CHECK_GLU version to 2.3.

2008-11-10  braden.mcdaniel

	* configure.ac: Updated package version to 20081110.

2008-11-09  braden.mcdaniel

	  variables; updated version to 2.4.
	* configure.ac: Updated package version to 20081109.
	* m4/ax_check_gl.m4, m4/ax_check_glu.m4, m4/ax_check_glut.m4:
	  Updated version numbers: AX_CHECK_GL to 2.3, AX_CHECK_GLU to 2.2,
	  AX_CHECK_GLUT to 2.1.

	  m4/ax_lang_compiler_ms.m4: Added an Emacs buffer-local variable
	  to set the mode to "autoconf".
	* m4/ax_check_glu.m4: Replaced some necessary quoting.
	* m4/ax_check_gl.m4, m4/ax_check_glu.m4, m4/ax_check_glut.m4:
	  Improve readability by avoiding gratuitous use of shell syntax.

2008-11-04  braden.mcdaniel

	* m4/ax_check_glu.m4: Use the C++ compiler when checking to see if
	  the GLU tesselator callback need the goofy varargs signature.

2008-10-30  braden.mcdaniel

	* m4/ax_check_gl.m4, m4/ax_check_glu.m4, m4/ax_check_glut.m4:
	  Reformatting for readability.

2008-10-19  braden.mcdaniel

	* m4/ax_check_gl.m4, m4/ax_check_glu.m4, m4/ax_check_glut.m4:
	  Require AC_PROG_SED and use .
	* m4/ax_check_gl.m4, m4/ax_check_glu.m4, m4/ax_check_glut.m4: Use
	  "#" for header comments instead of "dnl".

2008-10-06  braden.mcdaniel

	* configure.ac: Updated version to 20081006.
	* Makefile.am: svn2cl seems not to overwrite the ChangeLog; remove
	  it first.
	* m4/ax_check_gl.m4: .so's on platforms Nvidia targets are smart
	  enough to know about dependencies; the linker just needs to know
	  about the library location.

2008-10-05  braden.mcdaniel

	* configure.ac: Updated version to 20081005.
	* m4/acx_pthread.m4: Updated ACX_PTHREAD.

	* m4/ax_check_glu.m4: Accommodate nonstandard GLU tesselator
	  callback function type present on Mac OS X < 10.5.
	* COPYING, m4/ax_check_gl.m4, m4/ax_check_glu.m4,
	  m4/ax_check_glut.m4, m4/ax_lang_compiler_ms.m4: Added license
	  information.

	* configure.ac, m4/ax_check_gl.m4, m4/ax_check_glu.m4,
	  m4/ax_check_glut.m4: Modernization using AS_IF.

	  version to 1.1; incremented AX_CHECK_GLUT version to 1.7.

2004-09-14  braden

	* m4/ax_check_glut.m4: GLUT_LIBS should include GLU_LIBS regardless
	  of whether glut depends on X.

2004-09-13  braden

	* m4/ax_check_gl.m4, m4/ax_check_glut.m4: Mac OS X gcc -framework
