	* aclocal.m4: Regenerate.
	* configure: Ditto.
	* autogen.sh: New script.

	Always use "VERBOSE" setting.
	(MINGW_CXX): Don't include CFLAGS in definition.
	(all): Define target first, before everything else so that it is the
	default.
	(ps.exe): Don't add useless -lcygwin.
	(ldh.exe): For consistency, add to existing MINGW_LDFLAGS rather than
	redefining them.
	(cygcheck.exe): Always include -lz for MINGW_LDFLAGS.  Don't try to
	figure out where to find it.
	(dumper.exe): Simplify check.  Assume libraries are installed rather
	than trying to retrieve from source tree.
	(install): Just use /bin/mkdir to create directories.
	(Makefile): Regenerate when standard dependencies change.
	* dump_setup.cc: Always include zlib.h.  Remove accommodations for it
	possibly not existing.

	binutils package.
