What OS and gcc version are you using?
The bootloaders should generally be compiled using the same gcc that is 
included with the Arduino package (4.3.x, I think.)

running on ubuntu oineric.

The fix I think is better code and compiles fine with 4.3.2 as well as 4.5.3, 
so imho should be pulled, but then I would say that as I made the pull request.

49#hardware/arduino/bootloaders/atmega/ATmegaBOOT_168.c are the changes btw, if 
it's easier to see them direct.

With the avr-gcc contained inside the IDE it will compile perfectly.
Looks like that in the newer avr-libc toolchains the EEPROM write bit is 
changed from EEWE to EEPE as described above and in this forum topic: 
http://arduino.cc/forum/index.php/topic,37338.0.html

If you want to compile with the your system avr-gcc, you should modify the 
ATmegaBOOT_168.c file in line 586 to use the EEPE bit instead the EEWE.

Otherwhise in the makefile in the environment variable called "CC" add the path 
to the avr-gcc contained inside the IDE: 
CC = PATH_TO_ARDUINO_IDE/hardware/tools/avr/bin/avr-gcc
