* Fix a build problem with clang and --with-opt-dir.knu2014-03-211-1/+4
| | | | | | | | | | | | | | | * configure.in: Fix a build problem with clang and --with-opt-dir. If ruby is configured with --with-opt-dir=dir when using clang as compiler, a warning `clang: warning: argument unused during compilation: '-I dir'` is emitted almost every time clang compiles a file. Unfortunately, RUBY_CHECK_PRINTF_PREFIX takes any output from the compiler as fatal error, and the check thus fails due to the warning. This is an attempt to fix the problem by adding a flag -Qunused-arguments to CFLAGS locally in the function to suppress the warning.
