Here is how I decided to have a special case for this type of ifdef
1) Nios2 isn't included in a production release of RTEMS
2) We will soon use RTEMS/Nios2 in a production installation
3) Currently I have to continuously back-patch the RTEMS main 
trunk Nios2 patches into the RTEMS 4.10 version and that requires 
some continuing effort. It's much easier to maintain a Nios2
support code that works on both in RTEMS 4.10 and also the 
main trunk.

Making this type of ifdef work correctly did require some effort;
I am a bit new with the gnu build system.

I am requesting that we use this type of ifdef in the Nios2 specific 
code only until such a time that the Nios2 specific code can obtain 
a citizen status in RTEMS.

I completely agree that the ifdef should be 100% removed after 
Nios2 shows up in a released branch of RTEMS; at that time I
will have two places in git to maintain both the production 
version and the main trunk version which will allow a typical
type of develop-quickly-on-the-main-trunk and polish-on-the-
production-branch approach to quality control which is not 
currently possible.
