   3 Subject: configure: Move all includes to the first argument of AC_TRY_LINK
   4
   5 Putting includes in the second argument of AC_TRY_LINK is not safe. If
   6 a header having inline functions is included inside the main function,
   7 it becomes a nested function. This is not supported by clang.
