[svn-r907] Changes since 19981111

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

./INSTALL
	Added instructions about specifying a path for GNU zlib and
	HDF4 headers and library.

	Added comments for each of the tool names.  Added h5toh4 as a
	tool name.

./configure.in
./conigure		[REGENERATED]
./src/H5config.h.in	[REGENERATED]
	The config/* scripts get invoked with $CC_BASENAME set the
	base name of the compiler in order to make it easier to handle
	setting compiler flags for different compilers in a big case
	statement.  For instance, if $CC has the value

	    /usr/local/mpi/bin/mpicc -ansi -64

	then $CC_BASENAME will be `mpicc'.  The $CC_BASENAME is not
	set if $CC is not set.

	Fixed alignment in `configure --help'.

	An include and/or library path can be specified for GNU zlib
	if configure can't find it in normal places.  The "normal"
	means wherever your compiler normally searches, including
	search paths you've added through environment variables like
	CPPFLAGS and LDFLAGS.  The INSTALL file has instructions.

	The `-ljpeg' library is detected.

	If `ssize_t' is not found then a #define is added to
	H5config.h similar to what we already do for `size_t'.

	We detect the hdf5 header file `mfhdf.h' and libraries
	`-lmfhdf' and `-ldf' and if found define the H5TOH4 and
	TESTH5TOH4 Makefile variables.  The user can specify an
	include and/or library path. The INSTALL file has
	instructions.

	The `RUNTEST' variable has been split into `RUNSERIAL' and
	`RUNPARALLEL' because these are different commands.  The
	makefile still uses `RUNTEST', which defaults to the RUNSERIAL
	value.  The new testpar/Makefile.in sets RUNTEST to the
	RUNPARALLEL value. The default RUNSERIAL value is empty and
	the default RUNPARALLEL value is `mpirun -np 2'.  These can
	both be overridden in the config/* files.  To make the value
	the empty string set it like `RUNPARALLEL=none' in the
	config/* file.

	The new testpar/Makefile is generated from testpar/Makefile.in

./config/commence.in
	Added the RUNSERIAL and RUNPARALLEL makefile definitions.

./src/Makefile.in
	The `H5detect' program is run with RUNSERIAL, which is empty
	on all platforms except intel-osf1 (ASCI/Red)

./config/conclude.in
	Removed the `.c.a:' implicit rule -- we don't use it any more.

./config/BlankForm
./config/alpha-dec
./config/alpha-dec-osf4.0
./config/freebsd2.2.7
./config/hpux10.20
./config/hpux9.03
./config/intel-osf1
./config/irix5.3
./config/irix6.2
./config/irix64
./config/linux
./config/powerpc-ibm-aix4.2.1.0
./config/rs6000-ibm-aix4.1.4.0
./config/solaris2.5
	All of these files have been updated to hande multiple
	compilers. Most of them assume `cc' if CC is not set. The
	documentation in `BlankForm' has been updated and
	documentation in the other files refer to `BlankForm'.

	The intel-osf1 uses LDFLAGS instead of LIBS to specify the extra
	library search paths.

./examples/Makefile.in
./test/Makefile.in
./tools/Makefile.in
	Simplified by grouping some dependency information together
	more succinctly.

	The tools Makefile.in has been modified to work with the
	`h5toh4' and `testh5toh4' programs.  Until Paul checks these
	in you may have problems compiling.  If so, just create files
	h5toh4.c and testh5toh4.c that contain:

	    #include <stdio.h>
	    int main(int argc, char *argv[]) {
	        fprintf(stderr, "%s: not implemented\n", argv[0]);
		return 1;
	    }

./src/H5public.h
	Removed definition for `ssize_t' since this is now handled by
	configure in H5config.h with a #define.


./MANIFEST
./testpar/Makefile.in	[NEW]
	Added a makefile for parallel tests.  As soon as we get this
	working properly we can remove the other four makefiles in
	that directory and maintain just one.

 # Choosing a C Compiler

+# environment variable to the name of the compiler and any switches it 
+# requires for proper operation.  If CC is unset then this script may
+# set it.  If CC is unset by time this script completes then configure 
+# will try `gcc' and `cc' in that order (perhaps some others too).
+#
+# Note: Code later in this file may depend on the value of $CC_BASENAME
+#       in order to distinguish between different compilers when
+#       deciding which compiler command-line switches to use.  This
+#       variable is set based on the incoming value of $CC and is only
+#       used within this file.
