in this case actually, the error is in libsdl
the configure check for dlvsym presence is pretty pointless, it currently
always detects it
AC_TRY_COMPILE([
#include <stdio.h>
#define __USE_GNU
#include <dlfcn.h>
],[
dlvsym(NULL,"","");
],[
use_dlvsym=yes
])
since it's merely compiling, the warning about dlvsym being implicitly
declared doesnt trigger a failure
find attached a patch to fix this
