- *
- * * 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.
