suspect of bug

[Gerardo Enrique Paredes Mancia]

when using bison on a file i get this:

bison -y ./src/common/parser.y
./src/common/parser.y:101.6: parse error, unexpected ":", expecting ";" or "|"
./src/common/parser.y:113.26-53: invalid $ value
./src/common/parser.y:113.26-53: $5 of `arg' has no declared type
./src/common/parser.y:113.26-114.73: invalid $ value
./src/common/parser.y:113.26-114.73: $5 of `arg' has no declared type

however in those lines i don't see anything wrong


100: arg1    :       WORD
101:                        {$$ = wxmake_word($1); free($1);}
102:        |       STRING
103:                        {$$ = wxmake_string($1); free($1);}
102:        |       INTEGER
103:                        {$$ = wxmake_integer($1); free($1);}
104:        |       INTEGER PERIOD INTEGER
105:                        {$$ = wxmake_real($1, $3); free($1); free($3); }
106:        |       INTEGER EXP INTEGER
107:                        {$$ = wxmake_exp($1, $3); free($1); free($3); }
108:        |
109:              INTEGER PERIOD INTEGER EXP INTEGER
110:                         {$$ = wxmake_exp2($1, $3, $5); free($1);free($3);
111:                                                                free($5);}
112:        |       expr
113:                        {$$ = $1;}
        ;
i got this error compiling wxWindows-2.3.1 on FreeBSD-4.6-STABLE using bison 
1.75, this problem did not ocurred on prior versions of Bison, so i suspect 
must be a bug.
