 *
 * FILE_LOCAL   marks functions which are referenced only in the

 *              by "extern" statements elsewhere.
 *
 * OK_DOLLAR    Should be set TRUE if $ is a valid alphabetic character
 *              in identifiers (default), or zero if $ is invalid.

 *              sizeof (unsigned int), you will have to edit code and
