It is a bit of a annoyance that kenc will try to expand
function like macros on any symbol with the same name
and then complain when it doesnt see the '(' in the
invocation.
test case below:
void
foo(int)
{
}
struct Bar
{
int baz; /* <- should not conflict */
};
void
main(void)
{
baz(123);
}

add a buffer size argument to macexpand() and check for
overflow.
check for overflow when parsing #include directives.

for gethunk() to work, all allocators have to use it,
including allocations done by libc thru malloc(),
so the fake allocation functions are mandatory for
everyone.
to avoid duplication the code is moved to cc/compat
and prototypes provided in new cc/compat.h header.

Without an explicit signal for a truncation, copy propagation will
sometimes propagate a 32-bit truncation and end up overwriting uses of
the original 64-bit value.
This was independently discovered and fixed in Go. See:
http://golang.org/issue/1315
https://codereview.appspot.com/6002043/
Thanks Charles Forsyth for tips and advice.
