[svn-r1117] Changes since 19990303

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

./configure.in
./configure		[REGENERATED]
	The path for a command is calculated explicitly the hard way
	because `type -path' isn't portable.

./config/freebsd
./config/linux-gnu
./config/linux-gnulibc2
	Changed the way files reference each other.

./config/gnu-flags	[NEW]
./config/dec-flags	[NEW]
	These files figure out what flags to pass to certain compilers
	so we can reuse code in more than one config/* file.  They
	also have better warning messages when old compilers are used.

./config/linux-gnulibc1
./config/dec-osf4.x
	These files use the new *-flags files.


./src/H5D.c
./src/H5Onull.c
./src/H5Tconv.c
./tools/h5ls.c
	Fixed a compiler warning.

./src/H5detect.c
	Added a better comment to the top of the generated file.
