[libvirt] [PATCH] build: avoid compiler warning

According to GCC, ATTRIBUTE_UNUSED means that an attribute _might_ be unused, not _must_ be unused. Therefore, it is easier to blindly mark a variable, than to try and do preprocessor limiting of when we know it is unused. * src/remote/remote_driver.c (remoteAuthenticate): Mark attribute as potentially unused. Reported by Gustovo Morozowski. --- Thanks for the report. This would fix it, but I'd like to hear from others whether my patch is okay, or whether we need a more complex patch that uses #if to limit when the attribute is applied. src/remote/remote_driver.c | 9 +++------ 1 files changed, 3 insertions(+), 6 deletions(-) diff --git a/src/remote/remote_driver.c b/src/remote/remote_driver.c index e3df27b..44d8c26 100644 --- a/src/remote/remote_driver.c +++ b/src/remote/remote_driver.c @@ -6475,12 +6475,9 @@ done: /*----------------------------------------------------------------------*/ static int -remoteAuthenticate (virConnectPtr conn, struct private_data *priv, int in_open, - virConnectAuthPtr auth -#if !HAVE_SASL && !HAVE_POLKIT - ATTRIBUTE_UNUSED -#endif - , +remoteAuthenticate (virConnectPtr conn, struct private_data *priv, + int in_open ATTRIBUTE_UNUSED, + virConnectAuthPtr auth ATTRIBUTE_UNUSED, const char *authtype) { struct remote_auth_list_ret ret; -- 1.6.6.1
