	Renamed the old H5T_NATIVE_CHAR type to H5T_NATIVE_SCHAR to
	denote that it is always signed.

	Added a new H5T_NATIVE_CHAR type which has the same range,
	representation, and behavior as either H5T_NATIVE_SCHAR or
	H5T_NATIVE_UCHAR depending on the compiler and its
	command-line switches for the application source file which
	references H5T_NATIVE_CHAR. If source files are compiled with
	different switches then each source file will resolve
	H5T_NATIVE_CHAR appropriately so it matches the C type `char'
	in that source file.

	NOTE: THERE ARE OTHER DOCUMENTATION FILES THAT I DIDN'T CHANGE
	BECAUSE I CAN'T MODIFY THE SOURCE.

./test/extend.c
	Swapped two lines to prevent diagnostic messages from messing
	up the formatted output.
