Re: Bison Bug - Compiling Xfree86

| xftgram.y:161.8-168.6: type clash (`' `ival') on default action

Thanks for the report.  You should sent it to the XFree86 team since:

    65  %type  <dval>   number

   161  matrix  :   OS number number number number CS
   162                  {
   163                      matrix.xx = $2;
   164                      matrix.xy = $3;
   165                      matrix.yx = $4;
   166                      matrix.__REALLY_YY__ = $5;
   167                  }

A `;' is missing here.

   168  number  :   INTEGER
   169                  { $$ = (double) $1; }
   170          |   DOUBLE
   171          ;

Bison 1.35 did complain :(
