* */*.cs : scrub for StringToPtrAnsi and string usage in DllImports. * */*.custom : begin the scrub here too. * generator/ConstStringGen.cs : implement IManualMarshaler and move to 100% IntPtr marshaling. * generator/Ctor.cs : call Body.Finish too. * generator/IManualMarshaler.cs : new interface for generatables that marshal manually and need cleanup. * generator/Makefile.am : new file. * generator/MethodBody.cs : use IManualMarshaler if applicable. svn path=/trunk/gtk-sharp/; revision=41579
