Hi,
The following patches makes sure we can use gcc -Wstack-usage
to check there is no unbounded stack usage. This is mostly done by
changing unbounded alloca or dynamic stack arrays into a fixed bounded
stack array or just calling malloc and free directly.
The last patch adds -Wstack-usage to eu.am enabled by default.
All the library code now compiles without stack-usage warnings.
Most of the src tools files don't yet. Exceptions have been added
to src/Makefile.am. I hope to eventually be able to build everything
with bounded stack usage that the compiler can check.
Cheers,
Mark

I pushed this patch series, with the changes suggested by Roland,
to master now.
