Subject: debug: Add macro to mark variables that are only used in DBG statements
X-Git-Tag: 5.9.11rc1~12^2~52
X-Git-Url: http://git.ipfire.org/gitweb/gitweb.cgi?a=commitdiff_plain;h=2d4a98d0d33f688378612531c52d965513f7bc96;p=thirdparty%2Fstrongswan.git

debug: Add macro to mark variables that are only used in DBG statements

Some variables that are only assigned to be used in DBG statements
will otherwise trigger a "set but not used" warning/error if DEBUG_LEVEL
is too low.
