That is an improvement.

That is a good idea to use -NDEBUG for the SPE cflags when building a 
release.  That shouldn't require any changes to the library itself, but 
should be a matter of configuration options.  I'll handle that in 
scripts/config.

Just to make sure I undertand the impact of including stdio: it is going 
to increase the SPE text size, which may result in our larger problem 
sizes being single buffered instead of double buffered.  However, it 
should not create a correctness issue, i.e. it shouldn't affect stack 
usage if an assertion is not thrown.

I don't know if the SPE system assert pulls in stdio, but I hope not 
since it doesn't actually print anything!

Yes, please do.
