List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Tue, 30 Oct 2012 20:32:52 -0000 -Wswitch-enum is a bit awkward if a switch statement is intended to handle just some of the named codes of an enumeration especially, and leave the rest to the default label. We already have -Wall, which enables -Wswitch by default, and per GCC documentation, "The only difference between -Wswitch and this option [-Wswitch-enum] is that this option gives a warning about an omitted enumeration code even if there is a default label." Drop -Wswitch-enum to not force listing all named codes of enumerations in switch statements that have a default label. --- This will be useful in the next patch. --- configure | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/configure b/configure index 232d847..ea8a1ad 100755 --- a/configure +++ b/configure @@ -536,7 +536,7 @@ fi WARN_CXXFLAGS="" printf "Checking for available C++ compiler warning flags...
