I'm compiling with -ffunction-sections and -fdata-sections, and 
linking with --gc-sections.

Don't know what that means, but if it helps reduce dead code and 
doesn't have any unintended consequences, sounds good!

I'm not really interested in that because its too blunt of an 
instrument.  I'd like to use TypeInfo, but only if I'm doing 
dynamic casts or other things that require such runtime 
information.  Also, I'd only want the TypeInfo for the types that 
need it in my binary.  I've said this before but I'll repeat:  I 
like TypeInfo; I just don't like dead code.
