./tools/testh5dump.sh
	Changes that allow hdf5 to be configured and compiled in a
	directory other than the source directory. This is especially
	useful if you want to concurrently compile with different
	compilers and/or compile flags, or if the hdf5 source is on
	read-only media like a CDROM.  The changes were surprisingly
	easy ;-) Here's what you can do now...

		  $ mkdir /tmp/build1  # or something
		  $ cd /tmp/build1
		  $ /cdrom/hdf5/configure # where ever the source is
		  $ make

	Paul, you'll have to change the testh5toh4 script similar to
	the way I changed testh5dump.sh.  I started working on it but
	then gave up because of a number of problems: (1) I had to
	comment out all the tests that let h5toh4 choose the output
	file name because it always tried to put the output file in
	the same directory as the input file, (2) if path names are
	used during the h4 dump then they interfere with the
	diff. The test works fine when run in the source directory,
	but try this instead:

	    $ gunzip <hdf5-1.1.67.tar.gz |tar xf -
	    $ chmod -R ugo-w hdf5-1.1.67
	    $ mkdir build
	    $ cd build
	    $ ../hdf5-1.1.67/configure
	    $ make check

	Dan, I didn't modify the pablo/Makefile.in because I have no
	way to test it. I think all you need to do is add a couple
	lines before the @COMMENCE@ line and add a couple search
	directories for header files. Anyway, it seems like almost an
	exact duplicate of the src/Makefile.in, so it shouldn't be a
	problem...

./Makefile.in
	Removes a few more temporary files during make clean and
	distclean.

./configure.in
	I fixed the creation of the time-stamp files so that the
	initial make doesn't have to regenerated all the makefiles
	(only GNU make users will see any change).

./src/H5R.c
	Changed a return type from `intn' to `int' for an API
	function.

./src/H5detect.c
	Added the volatile qualifier to a couple more variables.

./tools/h5tools.c
	Fixed a compiler warning about an unused local.

./tools/h5toh4.c
	Initialized `optind' to 1 because it's zero on my system. It
	should always be one on a unix system.

./tools/testh5toh4
	Redirected "broken pipe" messages to /dev/null so outut is
	formatted correctly.
