This is fixed in the 4.x source.  Search for "No_Key" in ada/*rtems*
and you will see how to get around this one.

Thanks to Arnaud for the tip. :)

There is an page on building gnat on the RTEMS Wiki.

With the 4.x source, the next issue is to get the RTS build to know 
where newlib is so you don't have to install C before attempting Ada.
