[svn-r635] Changes since 19980831

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

./Makefile.in
	Running `make distclean' will not fail if one of the
	subdirectories has already been cleaned.

./config/BlankForm
./config/irix5.3
	Cleaned it up more.  Added better support/documentation for
	systems that have more than one compiler.

./config/alpha-dec-osf4.0	[NEW]
	Added a new config file as a result of testing on Jim Reus's
	machine.

./test/chunk.c
	Scaled down the testing range so we can actually run it
	interactively.

./tools/h5import.c
	Included <unistd.h> to get rid of warning for close().

./src/H5detect.c
	Seg-faults on Linux for some reason when NDEBUG is defined, so
	I just undef it at the top of the source.

./test/big.c
	Added a fflush().

./tools/h5ls.c
	The `-d' flag now works even when `-v' isn't specified.

./examples/h5_chunk_read.c
./examples/h5_compound.c
./examples/h5_extend_write.c
./examples/h5_group.c
./examples/h5_read.c
./examples/h5_write.c
	Indented according to hdf5 standards.

	Fixed compiler warnings

+#			tools. Usually this list will exclude

+#			switches that turn on symbolic debugging
+#			support (like `-g').
+#
+# PROD_CFLAGS		Flags to pass to the compiler to create a

+#			usualy exclude symbolic debugging switches
+#			(like `-g') and include optimization switches
+#			(like `-O').
+#
+# PROFILE_CFLAGS	Flags to pass to the compiler to create a
+# PROFILE_CPPFLAGS	library suitable for performance testing (like 
+# 			`-pg').  This may or may not include debugging 
+# 			or production flags.
+#			
+# CFLAGS		Flags can be added to this variable which
+#			might already be partially initialized.  These 
+#			flags will always be passed to the compiler
+#			and should include switches to turn on full
+#			warnings.  HDF5 attempts to be ANSI and Posix
+#			compliant and employ good programming
+#			practices resulting in few if any
+#			warnings.
+#
+# Note:			Warning flags do not have to be added to CFLAGS
+#			variable if the compiler is the GNU gcc
+#			compiler or a descendent of gcc.
+#
+# Note:			The CFLAGS should contains *something* or else 
+#			configure will probably add `-g'.  For most
+#			systems this isn't a problem but some systems
+#			will disable optimizations in favor of the
+#			`-g'.
