Thanks :-)

Note that some things are painful to do right with extern "C". For instance,
the __stoa helper takes as argument a pointer to a function with a type that
depends on template arguments. As far as I can see, it is not possible to do
that for extern "C" functions (I posted a question about that on clc++m
yesterday), so that would mean rewriting this code differently. My guess is
that making extern "C" functions usable would require a few DR, or extern "C"
being part of the type will follow the example of "export" and be
deprecated/removed (the second option is more likely, even if that's yet
another change that hurts Oracle's compiler).
