PATCH: fix for jv-scan

[Tom Tromey]

I'm committing the appended patch.  It fixes a bug so that jv-scan can
recognize main when declared with an arguments like `String args[]'
(previously it only recognized the form `String[] args').

1999-01-05  Tom Tromey  <tromey@cygnus.com>

	* parse-scan.y (variable_declarator_id): Set or increment
	bracket_count.
	(bracket_count): New global.
	(formal_parameter): Handle case where bracket pairs trail variable
	declarator id.
