 104  * Revision 1.6  2004/02/18 02:51:59  steve
 105  *  Fix type mismatches of various VPI functions.
 106  *
 107  * Revision 1.5  2003/06/04 01:56:20  steve
 108  * 1) Adds configure logic to clean up compiler warnings
 109  * 2) adds acc_compare_handle, acc_fetch_range, acc_next_scope and
 110  *    tf_isetrealdelay, acc_handle_scope
 111  * 3) makes acc_next reentrant
 112  * 4) adds basic vpiWire type support
 113  * 5) fills in some acc_object_of_type() and acc_fetch_{full}type()
 114  * 6) add vpiLeftRange/RigthRange to signals
 115  *
 116  * Revision 1.4  2003/05/30 04:18:31  steve

 119  * Revision 1.3  2003/02/17 06:39:47  steve
 120  *  Add at least minimal implementations for several
 121  *  acc_ functions. Add support for standard ACC
 122  *  string handling.
 123  *
 124  *  Add the _pli_types.h header file to carry the
 125  *  IEEE1364-2001 standard PLI type declarations.
 126  *
 127  * Revision 1.2  2002/08/12 01:35:02  steve
 128  *  conditional ident string using autoconfig.
