diagnostic.c (output_octal): Second parameter is unsigned.

2000-07-10  Gabriel Dos Reis  <gdr@codesourcery.com>

	* diagnostic.c (output_octal): Second parameter is unsigned.
	(output_long_octal): Likewise.
	(output_hexadecimal): Likewise.
	(output_long_hexadecimal): Likewise.
	(output_format): Adjust arguments extraction. Tweak.
	(output_verbatim, verbatim): End variable argument list.
	(report_diagnostic): Improve documentation.
