eldk-switch.sh should take care of that.

Yes it does. Thanks!

I got confused since behavior has changed from older ELDK versions:

----------
k1:/tmp$ eval `eldk-switch.sh -r 5.3  armv5te`
Setup for armv5te (using ELDK 5.3)
k1:/tmp$ arm-linux-gnueabi-gcc x.c
k1:/tmp$ eval `eldk-switch.sh -r 5.6 armv7a-hf`
Setup for armv7a-hf (using ELDK 5.6)
k1:/tmp$ arm-linux-gnueabi-gcc x.c
k1:/tmp$ eval `eldk-switch.sh -r 5.8 armv7a-hf`
Setup for armv7a-hf (using ELDK 5.8)
k1:/tmp$ arm-linux-gnueabi-gcc x.c
x.c:1:19: fatal error: stdio.h: No such file or directory
  #include <stdio.h>
                    ^
compilation terminated.
