[svn-r301] Changes since 19980226

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

./bin/release
	Changed default to not tag CVS sources.

./src/H5F.c
	Replaced a constant switch with preprocessor directives.
	Removed a local variable which was set but not used.

./src/H5Fprivate.h
	Changed `long long' to `int64' to get rid of ansi warnings in
	a few places.

	Fixed bugs in INT64DECODE() and UINT64DECODE() for big-endian
	architectures.  This fixes all the bugs with the Irix -64
	compile.

./src/H5F.c
	The default address and length sizes are set according to the
	sizeof(size_t) now that the bugs have been fixed.

./src/H5Fpublic.h
	Removed a trailing comma in an enumerated type.

./src/H5Fstdio.c
./src/H5Fsec2.c
	Added two more calls to fseek64() and lseek64(). Removed `long
	long' in place of `int64' to suppress -ansi warnings.

./src/H5P.c
	Replaced a FAIL with H5F_LOW_ERROR.

./src/H5private.h
./configure.in
	Increased version number to hdf5-1.0.1a since we've already
	released hdf5-1.0.0a.  Include <sys/types.h>.  Fixed
	indentation.  Fixed detection of off64_t for old Irix systems
	where it might be a struct.

./src/Makefile.in
	Moved a comment from the shell to the makefile since some
	versions of sh barf on interactive comments.

./config/linux
	Allow overriding of the CC variable from the command-line.  It
	still defaults to gcc but this allows us to specify a complete
	path from test scripts by saying:

	     CC=/usr/local/tools/gnu/gcc sh configure
