That interface is a slightly older one only used for tests (hence the
location of the header). The preferred API to use is:

#ifdef CYGFUN_KERNEL_THREADS_STACK_MEASUREMENT
cyg_uint32 cyg_thread_measure_stack_usage(cyg_handle_t thread);
#endif

Obviously enable the above config option. This version works better in that
it doesn't assume the stack is zero initialized.
