Here's the odd part.? I'm using 1.8.3 and it compiles cleanly without the
need for const.


Archiving built core (caching) in:
/tmp/arduino_cache_983837/core/core_arduino_avr_uno_58fdfaf47d105b38e1c8ebee0e7fc37d.a
Sketch uses 20150 bytes (62%) of program storage space. Maximum is 32256
bytes.
Global variables use 1288 bytes (62%) of dynamic memory, leaving 760 bytes
for local variables. Maximum is 2048 bytes.
