Comment (by normadize@…):

 I think there's somethign odd going on with clang. Command LIne tools are
 installed, as per
 {{{
 $ xcode-select --install
 xcode-select: error: command line tools are already installed, use
 "Software Update" to install updates

 $ gcc --version
 Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr
 --with-gxx-include-dir=/usr/include/c++/4.2.1
 Apple LLVM version 6.0 (clang-600.0.54) (based on LLVM 3.5svn)
 Target: x86_64-apple-darwin14.0.0
 Thread model: posix
 }}}

 It shows the gxx-include-dir to be the one that does contain stdarg.h but
 shouldn't the prefix be `/Library/Developer/CommandLineTools/usr` instead
 of `/Applications/Xcode.app/Contents/Developer/usr` ?

 Same goes for
 {{{
 $ xcode-select -p
 /Applications/Xcode.app/Contents/Developer
 }}}
 Should that be `/Library/Developer/CommandLineTools` ?

 Note that I download XCode 6.1 and the CLT 6.1 from the apple developer
 website and installed the pkg manually. I didn't do it from the App Store.
