Comment 1 Vladimir Kvashin 2007-02-12 18:31:52 UTC 
Parser does not fail any more;
but there are no information concerning this function forward declaration in model.
Comment 2 Vladimir Kvashin 2007-02-12 18:34:31 UTC 
Example with paramter has the same effect:

wo_2(int);

wo_2(int p) {
	return 0;
}
Comment 3 nnnnnk 2009-02-04 12:19:14 UTC 
There is no problems with definitions now.
Comment 4 Vladimir Voskresensky 2009-02-04 12:35:51 UTC 
in my case both examples show errors:
wo_2(int);
wo();
