In a few cases it does apply.  Not many though.

The bulk of the changes have been to use the compiler's knowledge of
what types are what, and do constant folding as appropriate, rather
than try to replicate this in the preprocessor and libstdc++ configury.
I estimate a total reduction in size of libstdc++ by at least 3000 lines.

Where's the best place to put this information?
