Thanks. There was no sign of config options to support Ada building
cross-avr-binutils, but I wondered. It's good to know that binutils is where to
focus, if need be...

Good point! It's not clear to me what needs to be cross-specific (beyond
compiler and assembler, obviously!) and which native tools will do, but the
preprocessor should be agnostic if anything is. So I'll try that first.

The pre-packaged cross-avr-gcc chain appears OK except for Ada support.

Rebuilding from source (loosely following the instructions on 
http://sourceforge.net/apps/mediawiki/avr-ada/index.php?title=Setup#Compiling_the_AVR-Ada_libraries
but adapting for 4.5) appears to be successful (i.e. complete with only minor
difficulty and no errors)

Compiling the AVR-Ada components is where I came unstuck. I'll try the symlink
next.

Thanks for the suggestion,
