I like this idea, but I'm not sure if it works -- does it handle
recursion in the initializer?


Interesting.  It works in the sense that a and t both get initialized
with correct values, but the mechanism for initialization is wildly
different.

Without my patch, you get static initializations like:

.globl a
       .data
       .align 4
       .type   a, @object
       .size   a, 16
a:
       .long   _ZN1S3fooEv
       .long   0
       .long   _ZN1S3barEv
       .long   0

With my patch, initialization is performed by
_Z41__static_initialization_and_destruction_0iifunction.

Looks like I've got some more work to do.
