Precompiler does not put function declarations near top

When, for example, I try to compile the example "ColorPalette" from the Fastled libary on my teensy 3.2 using arduino IDE 1.6.6 + TeensyDuino 1.26, I get the following errors:

Arduino: 1.6.6 (Windows 10), TD: 1.26, Board:"Teensy 3.2 / 3.1, Serial, 96 MHz optimized (overclock), US English"

Based on research (Fastled Issue) by the maintainer of the Fastled Libary it seems the Precompiler does not put function declarations near top for Teensy, Arduino Zero and Arduino Due.
