Thanks Paul,

It seems that you missed some. At least the one i'm facing in
yydestruct() definition (data/c.m4:389) :

m4_define_default([b4_yydestruct_generate],
[[/*-----------------------------------------------.
| Release the memory associated to this symbol.  |
`-----------------------------------------------*/

]$1([yydestruct],
    [static void],
    [[const char *yymsg],    [yymsg]],
    [[int yytype],           [yytype]],
    [[YYSTYPE *yyvaluep],    [yyvaluep]]b4_location_if([,
    [[YYLTYPE *yylocationp], [yylocationp]]]))[
{
  /* Pacify ``unused variable'' warnings.  */
  (void) yyvaluep;
]b4_location_if([  (void) yylocationp;
])[
  if (!yymsg)
    yymsg = "Deleting";
