Patch for java dir warnings

[Kaveh R. Ghazi]

The number of warnings in the java dir has crept up again.  This patch
squelches the following nits.

typeck.c:584: warning: function declaration isn't a prototype
typeck.c:584: warning: unused parameter `type'
verify.c:414: warning: `message' might be used uninitialized in this function
jcf-io.c:195: warning: comparison between signed and unsigned
jcf-io.c:216: warning: comparison between signed and unsigned
mangle.c:317: warning: `saved_current' might be used uninitialized in this function
jvspec.c:128: warning: `filelist_filename' might be used uninitialized in this function
jvspec.c:130: warning: `filelist_file' might be used uninitialized in this function


Only this one remains:

jvspec.c:70: warning: string length `756' is greater than the length `509' ISO C89 compilers are required to support


Bootstrapped on the trunk and the branch on solaris2.7 (both have
identical warning profiles for java.)

Ok to install on both?

		Thanks,

	* 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.
