* Revision 1.2 2001/09/10 19:21:13 brianp
* WindML updates (Stephane Raimbault)
*
* Revision 1.1 2001/08/20 16:07:11 brianp
* WindML driver (Stephane Raimbault)
*
* Revision 1.5 2000/12/24 22:53:54 pesco
* * demos/Makefile.am (INCLUDES): Added -I$(top_srcdir)/util.
* * demos/Makefile.X11, demos/Makefile.BeOS-R4, demos/Makefile.cygnus:
* Essentially the same.
* Program files updated to include "readtex.c", not "../util/readtex.c".
* * demos/reflect.c: Likewise for "showbuffer.c".
*
*
* * Makefile.am (EXTRA_DIST): Added top-level regular files.
*
* * include/GL/Makefile.am (INC_X11): Added glxext.h.
*
*
* * src/GGI/include/ggi/mesa/Makefile.am (EXTRA_HEADERS): Include
* Mesa GGI headers in dist even if HAVE_GGI is not given.
*
* * configure.in: Look for GLUT and demo source dirs in $srcdir.
*
* * src/swrast/Makefile.am (libMesaSwrast_la_SOURCES): Set to *.[ch].
* More source list updates in various Makefile.am's.
*
* * Makefile.am (dist-hook): Remove CVS directory from distribution.
* (DIST_SUBDIRS): List all possible subdirs here.
* (SUBDIRS): Only list subdirs selected for build again.
* The above two applied to all subdir Makefile.am's also.
*
* Revision 1.4 2000/09/08 21:45:21 brianp

/*
* Revision 1.2 2001/09/10 19:21:13 brianp
* WindML updates (Stephane Raimbault)
*
* Revision 1.1 2001/08/20 16:07:11 brianp
* WindML driver (Stephane Raimbault)
*
* Revision 1.5 2001/03/27 17:35:26 brianp
* set initial window pos
*
* Revision 1.4 2000/12/24 22:53:54 pesco
* * demos/Makefile.am (INCLUDES): Added -I$(top_srcdir)/util.
* * demos/Makefile.X11, demos/Makefile.BeOS-R4, demos/Makefile.cygnus:
* Essentially the same.
* Program files updated to include "readtex.c", not "../util/readtex.c".
* * demos/reflect.c: Likewise for "showbuffer.c".
*
*
* * Makefile.am (EXTRA_DIST): Added top-level regular files.
*
* * include/GL/Makefile.am (INC_X11): Added glxext.h.
*
*
* * src/GGI/include/ggi/mesa/Makefile.am (EXTRA_HEADERS): Include
* Mesa GGI headers in dist even if HAVE_GGI is not given.
*
* * configure.in: Look for GLUT and demo source dirs in $srcdir.
*
* * src/swrast/Makefile.am (libMesaSwrast_la_SOURCES): Set to *.[ch].
* More source list updates in various Makefile.am's.
*
* * Makefile.am (dist-hook): Remove CVS directory from distribution.
* (DIST_SUBDIRS): List all possible subdirs here.
* (SUBDIRS): Only list subdirs selected for build again.
* The above two applied to all subdir Makefile.am's also.
*
* Revision 1.3 2000/09/29 23:09:39 brianp
