[svn-r1363] Changes since 19990618
----------------------

./Makefile.in
	Running `make' in the top directory recurses into the examples
	directory also except if the make target is one of: lib,
	progs, check, test, _test, install, uninstall.

./examples/Makefile.in
	Changed programs into tests, which just means that `make
	tests' does what `make progs' used to do and that `make check'
	runs the executables.

./src/H5Tconv.c
	Fixed a typo in the unsigned-to-signed native converter for
	large types to small types. This fixes a bug on baldric and
	possibly other machines for the `dtypes' test.

	Also fixed a signed vs. unsigned warning.
