possible problem in BlinkWithoutDelay regarding constants

IMHO a warning should be displayed without Verbose compilation output.

With verbose set so many messages are output that the final status of the output window is filled with
...avr-ar rcs ...core.a ...*.c.o
"
"
...avr-gcc...
...avr-objcopy... elf ... epp
...avr-objcopy... elf ... hex
The final
Binary sketch size: 466 bytes (of a 32,256 byte maximum)
looks good.

The warning is scrolled off

Not user friendly.
