The major change is obviously in the versions of the used components:

* ELDK 3.1 is based on gcc version 3.3.3 and libc version 2.3.1
* ELDK 4.1 is based on gcc version 4.0.0 and libc version 2.3.5
  and for completeness:
* ELDK 4.2 is based on gcc version 4.2.2 and libc version 2.6

But that should not affect application code, assuming it was
implemented in a standard conforming way.

No changes of compile options are necessary.
