Don't populate const arrays on the stack but instead make them static.
Makes the object code smaller by over 1800 bytes:

Before:
   text    data     bss     dec     hex filename
  94100    9160       0  103260   1935c drxj.o

After:
   text    data     bss     dec     hex filename
  91044   10400       0  101444   18c44 drxj.o
