1999-06-29  Tom Tromey  <[e-mail]>

	* jvspec.c (lang_specific_driver): Recognize --help.

Fri Jun 25 13:35:19 1999  Alexandre Petit-Bianco  <[e-mail]>

	* parse.c: Rebuilt.

	* parse.y (resolve_package): Fixed bogus return statement.
	(patch_method_invocation): Resolve method invocation beginning with
 	a package name qualifier.

	(resolve_package): Search current and imported packages.
	(lookup_package_type_and_set_next): New function.

        instruction.  With some control flows it is possible that the last
        block ends with an `athrow'.
