Patch submitted on qpid-dev:

2006-12-05  Jim Meyering  <meyering@redhat.com>

	* gen/Makefile.am (timestamp): Remove unnecessary "; \",
	that could have obscured a failure.
	(gen-src.mk): Use echo 'var = '\\, rather than 'var = \'.
	Both work, but emacs' font-lock mode mishandles the latter.

	* bootstrap: Give JAVA and JAVAC default values, and export them.
	Don't define abs_srcdir; no longer needed.
	Also filter out gen/Makefile.am's echo warning: ...
	Add comments.
