1. Argument For: In the sample makefile I ship with WinAVR, I always 
put -lm in the linker flags. It doesn't hurt anything if it's not 
needed and it helps with Windows users who don't know the "Unix way" 
and forget to include the flag.

2. Argument Against: Good ol' Unix tradition. 

Which I would seriously look at how useful this tradition really is. 
In the end, it'll be up to the *nix people here if they are willing 
to break with history. But I'm OK either way.
