OK: http://clang.llvm.org/docs/UsersManual.html#cl_diagnostics Of course, you can only suppress warnings; you cannot suppress actual errors. clang doesn't currently support -traditional aka pure K&R C. It's possible that compiling with -ansi aka -std=c89 might help-- at least you should get -Wno-implicit-function-declaration and maybe -Wno-implicit-int. > Also, why is this an error: > error: non-void function 'top_button_cross' should return a value > [-Wreturn-type] > when most everything else is a warning. (See > http://pointyhat.freebsd.org/errorlogs/amd64-errorlogs/e.9-exp.20110616185105/xppaut-5.99.log.) top_button_cross() probably should be declared as returning void. What's presumably happening is that it gets a default return type of int since it doesn't otherwise specify a return type, and then fails to have an explicit return, which is an error.
