 New flex warnings With GCC 4.3, I get warnings from every flex scanner that 'input' is defined but not used. This can be solved by adding %option noinput. I tested this option with a current flex and with the old 2.5.4a; both accept it. See attached patch. Does anyone see problems with this? -- Sent via pgsql-patches mailing list (pgsql-patches@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-patches      |

Hm, I wonder why we didn't see those before ... [ looks at code... ] Oh: yyinput() recurses internally, so even though it's not called from anywhere else, older gcc's don't realize it's really unreferenced. I confirm 2.5.4 has the noinput option. Patch seems ok from here, regards, tom lane -- Sent via pgsql-patches mailing list (pgsql-patches@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-patches |
