Yes, those are the docs - you did:

  dadix 2.6.28-13-generic ~/home/kin/coding$ arm-linux-gnueabi-gcc -mabi=apcs-gnu test.c -o test
  dadix 2.6.28-13-generic ~/home/kin/coding$ arm-linux-gnueabi-gcc test.c -o

Notice the difference?

Ah, so all you want is the old ABI, not the GNUEABI?  Then you should
download ELDK 4.1 for arm:

[dzu at pollux dzu]$ eldk-switch -q
Currently using eldk 4.1 from /opt/eldk-4.1
[dzu at pollux dzu]$ ${CROSS_COMPILE}gcc -o foo foo.c
[dzu at pollux dzu]$ ${CROSS_COMPILE}readelf -h foo | grep OS/ABI
  OS/ABI:                            ARM
[dzu at pollux dzu]$ 


Q:  What does FAQ stand for?
