Follow-up Comment #1, bug #32650 (project avr-libc):
The math library is not needed if you do not pass a variable to _delay_ms (or
_delay_us) as the instructions to avr-libc warn you not to do. Only constants
can be supplied to the delay functions.
In fact, following your path will bring in the floating-point library
unnecessarily and will cause the delay functions to generate far more delay
that requested.
For more on the use of the delay functions, please read
