 129  * 2) adds acc_compare_handle, acc_fetch_range, acc_next_scope and
 130  *    tf_isetrealdelay, acc_handle_scope
 131  * 3) makes acc_next reentrant
 132  * 4) adds basic vpiWire type support
 133  * 5) fills in some acc_object_of_type() and acc_fetch_{full}type()
 134  * 6) add vpiLeftRange/RigthRange to signals
 135  *
 136  * Revision 1.6  2003/05/30 04:18:31  steve
 137  *  Add acc_next function.
 138  *

 153  *  acc_ functions. Add support for standard ACC
 154  *  string handling.
 155  *
 156  *  Add the _pli_types.h header file to carry the
 157  *  IEEE1364-2001 standard PLI type declarations.
