   VARIABLE  I/O  DESCRIPTION 
   --------  ---  -------------------------------------------------- 
   small      I   Limiting measure of small gaps. 
   window    I,O  Window to be filled. 

   small       is the limiting measure of the small gaps to be 
               filled. Adjacent intervals separated by gaps of 
               measure less than or equal to small are merged. 

   window      on input, is a window containing zero or more 
               intervals. 

               window must be declared as a double precision SpiceCell.

   window      on output, is the original window, after adjacent 
               intervals separated by small gaps have been merged. 

   None. 

   This routine removes small gaps between adjacent intervals 
   by merging intervals separated by gaps of measure less than 
   or equal to the limiting measure small. 

   Let window contain the intervals 

      [ 1, 3 ]  [ 7, 11 ]  [ 23, 27 ]  [ 29, 29 ] 

   Then the following series of calls 

      wnfild_c (  1, &window );                        (1) 
      wnfild_c (  2, &window );                        (2) 
      wnfild_c (  3, &window );                        (3) 
      wnfild_c ( 10, &window );                        (4) 

   produces the following series of windows 

      [ 1,  3 ]  [ 7, 11 ]  [ 23, 27 ]  [ 29, 29 ]     (1) 
      [ 1,  3 ]  [ 7, 11 ]  [ 23, 29 ]                 (2) 
      [ 1,  3 ]  [ 7, 11 ]  [ 23, 29 ]                 (3) 
      [ 1, 29 ]                                        (4) 

    None. 

   1) If the input window does not have double precision type,
      the error SPICE(TYPEMISMATCH) is signaled.

   2) If small is less than or equal to zero, this routine has 
      no effect on the window.

   None.
