* examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc: Remove from CVS. These files are automatically generated. * examples/extexi: Clarify that this file is now part of Bison, not GNU M4, and that it works with any POSIX-compatible Awk. * examples/calc++/Makefile.am (run_extexi): Remove; not used. ($(calc_extracted)): Renamed from $(calc_sources_extracted), so that we also get calc++-parser.yy. Geneate it. Use $(AWK), not gawk, since any conforming Awk will do. Put comment before action, since older 'make' can't handle comment in action. $(BUILT_SOURCES): List all built sources, not just some of them. $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources. $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT. $($(calc_sources_generated)): Remove unnecessary test for existence of target. (This had a shell syntax error anyway; a stray "x".) (calc_extracted): List $(srcdir)/calc++-parser.yy, not calc++-parser.yy. * examples/.cvsignore, examples/calc++/.cvsignore: New files.
