Tested with -ffunction-sections and -fdata-sections, neither make any 
difference. Funny thing is, not all my PROGMEM data is being thrown away, 
only two unreferenced ones. I suppose the linker's technically justified in 
removing them, but is there a way to indicate that I want *all* PROGMEM 
variables preserved, no matter what? Adding the used attribute didn't help, 
either.
