Fix bug#1379: don't use alloca() where it could overrun the stack size.

Implemented enhancement #1391: allow "export" in target-specific
variable definitions.

Change the Info name of the "Automatic" node to "Automatic Variables".
Add text clarifying the scope of automatic variables to that section.
