[avr-libc-dev] Patches for 1.7.1?

[Ruud Vlaming]

On Atmels website:

  
http://distribute.atmel.no/tools/opensource/as5-beta/avr8-gnu-toolchain-3.2.0.255-source.zip

there are patches for libc 1.7.1

  40-avr-libc-1.7.1-xmega32X1.patch
  41-avr-libc-1.7.1-xmega128b1.patch
  42-avr-libc-1.7.1-bug_11793_fix.patch
  50-avr-libc-1.7.1-atxmega256a3bu.patch
  51-avr-libc-1.7.1-at90pwm161.patch
  52-avr-libc-1.7.1-atmega32_5_50_90_pa.patch

But version 1.7.1 is very new and does it need patching?

Furthermore, the first two patches (40, 41) can be applied, 
but compilation results in an error:
 ... avr-libc-1.7.1/crt1/gcrt1.S:179: Error: non-constant expression in ".if" 
statement
The last application cannot be applied at all:
  patching file ./include/avr/power.h
  Hunk #1 FAILED at 74.
  Hunk #2 FAILED at 146.
  Hunk #3 FAILED at 170.
  Hunk #4 FAILED at 254.
  Hunk #5 FAILED at 338.

I am curious at your opinion.
