Re: [Flex-devel] Spurious compiler warning when building PostgreSQL

[Peter G. <pe...@2n...>]

Thanks for your efforts Peter.

I'm disappointed to report that it does not. Here is the context of
the warning, within scan.c:

/* yy_try_NUL_trans - try to make a transition on the NUL character
 *
 * synopsis
 *      next_state = yy_try_NUL_trans( current_state );
 */
    static yy_state_type yy_try_NUL_trans  (yy_state_type
yy_current_state , yyscan_t yyscanner)
{
        register int yy_is_jam;
    struct yyguts_t * yyg = (struct yyguts_t*)yyscanner; /* This var
may be unused depending upon options. */

        register int yy_c = 256;
        register yyconst struct yy_trans_info *yy_trans_info;

        yy_trans_info = &yy_current_state[(unsigned int) yy_c];
        yy_current_state += yy_trans_info->yy_nxt;
        yy_is_jam = (yy_trans_info->yy_verify != yy_c);

        return yy_is_jam ? 0 : yy_current_state;
}

Perhaps that helps?

Thanks
