I have check this.
The Avr-gcc 4.2.3 and 4.3.0 have not any problems.
The Avr-gcc 4.1.2 and early are too agressive in manipulations
with 0 address (XMEGA's GPIO0 has address 0).
It is pity that GCC 4.1 branch is brocken.

What macroses must to use in source code?
__AVR_XMEGA__ or '__AVR_ARCH__ > 100'?
The 'common.h' uses '>= 100': what is arch 100 ?

I have find:
   Avr-libc 1.4: exp.S
   Avr-libc 1.6: frexp.S (fixed now)
It is needed to continue a check.
