Robb Matzke 2ab2e14bb5 [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
