 * as expected by the NWK object libraries. This allows the actual
 * ZMAIN function bodies to locate outside ROOT memory, increasing
 * space for user defined constants, strings, etc in ROOT memory.
 *
 * If the MINIMIZE_ROOT compile flag in not defined, the ZMAIN API
 * functions are aliased to the similarly-named function bodies and
 * located in the ROOT segment with no "jump function" overhead.
 * This is the default behavior which produces smaller overall code
 * size and maximizes available code space in BANK1...BANK3.
