Details:

Compiling using gcc 4.5.2 against AVR LibC 1.7.1 results in calls to _delay_ms
failing with:

c:\program files (x86)\mhv avr
tools\bin\../lib/gcc/avr/4.5.2/../../../../avr/include/util/delay.h: In
function 'void _delay_ms(double)':
c:\program files (x86)\mhv avr
tools\bin\../lib/gcc/avr/4.5.2/../../../../avr/include/util/delay.h:149:42:
error: 'fabs' was not declared in this scope
c:\program files (x86)\mhv avr
tools\bin\../lib/gcc/avr/4.5.2/../../../../avr/include/util/delay.h:149:43:
error: 'ceil' was not declared in this scope

Adding math.h to the list of includes in util/delay.h fixes the problem.
