2002-03-23 Martin Baulig <martin@gnome.org>

	* SignatureHelper.cs (GetFieldSignatureHelper, GetLocalSignatureHelper):
	Implemented.

	* LocalBuilder.cs (LocalBuilder): This internal constructor now takes
	a ModuleBuilder argument instead of a ISymbolWriter one.
	(SetLocalSymInfo): Create and pass type signature to DefineLocalVariable.
