 Does this work:
 {{{
      -I<dir>         - Look for SWIG files in directory <dir>
 }}}
 Also:
 {{{
      -importall      - Follow all #include statements as imports
      -includeall     - Follow all #include statements
 }}}

 separate struct defns it builds ok.

 How about:

 {{{
 struct _Color_Value_
 {
     DCELL value;
     unsigned char red;
     unsigned char grn;
     unsigned char blu;
 };

 struct _Color_Rule_
 {
     struct _Color_Value_ low, high;

     struct _Color_Rule_ *next;
     struct _Color_Rule_ *prev;
 };
 }}}
