If you're not interested in a precise number, but can accept a measure 
that would indicate the stack depth in bytes you can obtain the address 
of one of the function's plain local variables through the & operator 
and cast it to a char * pointer.  I've used this technique to track the 
use of stack space during the runtime of a program; see the snapshots at 
<http://www.spinellis.gr/codequality/stack.gif?clcpp>.  This technique 
is not portable, but will work on most computer architectures.
