Reasons?

A year or so ago we had to *add* an __init to a declaration, because
one architecture was generating a short-mode-addressing relative branch
to the callee, assuming the target was in the same section as the call
site.  When the linker went to resolve the branch, it discovered that
the target was in fact in a different section and was too far away to
be able to use the short-mode addressing.  IIRC, that architecture was
arm.
