Hey

Ignore my previous post now using:

"\n"                    { return NEWLINE; }
"    "+                 {
                          int top_len = VEC_index( gpy_int, gpy_indent_stack,
						   VEC_length( gpy_int, gpy_indent_stack )-1 );
			  int indent = yyleng/4;

			  if( top_len <= indent )
			    {
			      if( top_len != indent )
				{
				  VEC_safe_push( gpy_int, gc, gpy_indent_stack, indent );
				}
			      return INDENT;
			    }
			  else if( top_len > indent )
			    {
			      VEC_pop( gpy_int, gpy_indent_stack );
			      return DEDENT;
			    }
                         }

<<EOF>>                {
                         int top_len = VEC_index( gpy_int, gpy_indent_stack,
						  VEC_length( gpy_int, gpy_indent_stack )-1 );
			 if( top_len != 0 )
			   {
			     VEC_pop( gpy_int, gpy_indent_stack );
			     return DEDENT;
			   }
			 else
			   return 0;
                       }

Didnt realise yyleng records the entire length of matched rules when
using <something>+ it recorded the entire length of it so all i needed
to do was divide.
