Subject: [PATCH] jcf-io.c (read_zip_member): Cast to long in comparison with
 signed value.

	* jcf-io.c (read_zip_member): Cast to long in comparison with
	signed value.

	* jvspec.c (lang_specific_driver): Initialize variables.

	* mangle.c (find_compression_record_match): Likewise.

	* typeck.c (build_null_signature): Provide static prototype.  Mark
	parameter with ATTRIBUTE_UNUSED.

	* verify.c (verify_jvm_instructions): Initialize variable.
