AFAIK these sections are only loaded read-only for things like code
so this probably won't work.  If you have too many global variables to
fit in the data segment, you should probably use dynamic memory for
them instead.

Multi-segment support for read-only data like strings, and static const
arrays is a different thing, see my posts from January.  AFAIK there is
still the bug I mentioned in these posts.
