If I use a named break in the D code (that OUTER), to avoid the goto, the running speed is essentially the same.

The first thing that comes to mind: "For the Nth time, someone thinks 
language X is 'faster' than language Y because of a comparison between 
compilers with completely different backends (and thus optimizers), even 
though there are pairs of compilers that use the same backend for either 
language."

Try comparing DMC vs. DMD, or GCC vs. GDC...
