This was a problem in the implementation of OS9 for the 68k. The fix involved
a smart code generator for the C compiler. The limitation is that a single
function may not be larger than 64k (at least in the initial implementation).
Anyone that would write a function that large is in trouble anyway (in my
opinion). The make it clearer, local variables are stored on the stack and
this segment is also limited  by the architecture on a per-function basis.
Global/external and static variables are stored in a preallocated static data
segment.

   Hope this helps,
