From f444e5286ee8986adb0899f85cc292fc2cd7cd04 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Fri, 4 Jul 2008 00:37:40 -0700 Subject: [PATCH] Work around gcc warnings from curl headers After master.k.org upgrade, I started seeing these warning messages: transport.c: In function 'get_refs_via_curl': transport.c:458: error: call to '_curl_easy_setopt_err_write_callback' declared with attribute warning: curl_easy_setopt expects a curl_write_callback argument for this option It appears that the curl header wants to enforce the function signature for callback function given to curl_easy_setopt() to be compatible with that of (*curl_write_callback) or fwrite. This patch seems to work the issue around.
