[svn-r946] Changes since 19981121

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

./src/H5Tconv.c
	With my poor eyesight I missed the definitions of SCHAR_MIN
	and SCHAR_MAX in <limits.h> and used CHAR_MIN and CHAR_MAX
	incorrectly. I changed all occurrences of the latter to the
	former and the new hardware integer type conversions now work
	on Irix.

./configure.in
./configure		[REGENERATED]
./src/H5config.h.in	[REGENERATED]
./src/H5private.h
./src/H5.c
./test/h5test.c
	Added a wrapper for HDsnprintf() that just calls sprintf() if
	snprintf() isn't available.

./MANIFEST
	Added Paul's new h5toh4 files.

 /*-------------------------------------------------------------------------
+ * Function:	HDsnprintf
+ *
+ * Purpose:	Writes output to the string BUF under control of the format
+ *		FMT that specifies how subsequent arguments are converted for
+ *		output.  It is similar to sprintf except that SIZE specifies
+ *		the maximum number of characters to produce.  The trailing
+ *		null character is counted towards this limit, so you should
+ *		allocated at least SIZE characters for the string BUF.
+ *
+ * Note:	This function is for compatibility on systems that don't have
+ *		snprintf(3). It doesn't actually check for overflow like the
+ *		real snprintf() would.
+ *
+ * Return:	Success:	Number of characters stored, not including
+ *				the terminating null.  If this value equals
+ *				SIZE then there was not enough space in BUF
+ *				for all the output.
+ *
+ *		Failure:	-1
+ *
+ * Programmer:	Robb Matzke
