Those aren't specializations, they're overrides. Just use
extern bool ascending_compare (double, double);
without the template<> here and define the functions elsewhere.
Overrides in the active namespaces are found first, iirc.

With g++ 4.3? It compiled octave, ran the tests, and let me
poke at the xGELSD problem. ;) I didn't look further.
