>using const helps gcc to move these data to the text segment

This may sound terrible, but indeed the data that a
"pointer to constant" is pointing to is not (in general)
constant. Being a "pointer to constant" is a property of
the *pointer*, not of the *pointed data*.

Const pointers in interfaces are designed to be an help
for the (distracted) programmers, they can't be an help
for the compiler.

That const-ness really helps or not is another issue...
