/*
 * Macros to transparently switch between the stack and heap for large
 * allocations.  The former is useful on MMU systems as it results in
 * smaller code, but the latter is required on NoMMU systems.  This is
 * due to small stacks that cannot grow and so doing large allocs will
 * cause a stack overflow.
