to satisfy alignment requirements of members. Use NULL_TREE
when checking whether var_size is set.

1999-12-02 Mike Karr <mkarr@mathworks.com>
* cccp.c (argdata): Added free_ptr member.
(macroexpand): Initialize free_ptr of each argument. When an
argument's buffers are freed, if the argument's free_ptr corresponds
to a buffer on the input stack, then return the free_ptr to that stack
frame, otherwise, free it.
(macarg): If an argument begins and ends on the same input stack level,
then transfer the free_ptr of that buffer to the argument in case
the stack is popped during the processing of a subsequent argument.
