[svn-r213] Changes since 19980130

----------------------

./MANIFEST
	Added H5Fmpio.c.  One way to check that you've properly
	included new files is to run `./bin/release none', then unpack
	the resulting tar file somewhere and try to compile it.  The
	tar file will be ./releases/hdf-5.0.0a.tar.

./config/freebsd2.2.1
./config/linux
	Added `-ansi'

./acconfig.h
	Added definitions for PHDF5 and HAVE_PARALLEL.

./configure.in
	Added minimal support for parallel build.  Kim and Albert will
	have to flesh this out or I can do it if they're more specific
	about what they need.

./config/commence.in
	Added default value for $(RUNTEST)

./config/conclude.in
	`make test' uses value of $(RUNTEST) to run test cases.

./src/Makefile.in
	Added PARALLEL_SRC for conditional compilation of H5Fmpio.c

./src/H5D.c
./src/H5Dpublic.h
	Added H5Dget_type() for Elena


NOTE: These changes require that configure be rerun.  If you're using
      GNU make it will happen automatically, otherwise do it by
      hand.
