Description

4 years ago
Started with OS X 10.8.5, XCode 5.0.1, and an older clang:

$ ls -l `which clang`
-rwxr-xr-x  1 root  wheel  21622640 14 Nov  2012 /usr/bin/clang*
$ clang --version
Apple clang version 4.1 (tags/Apple/clang-421.11.66) (based on LLVM 3.1svn)
Target: x86_64-apple-darwin12.5.0
Thread model: posix

http://en.wikipedia.org/wiki/Xcode says this is from XCode 4.5.1 or 4.5.2.

'./mach bootstrap' installs a few things from homebrew (python 2.7.5, gdbm, sqlite) and declares success.

Building m-c fails (581d180a37f3):

Updated to Xcode 5.0.2, m-c still busted. 

Install Command Line Tools using XCode preferences UI:
$ ls -l `which clang-rwxr-xr-x  1 root  admin  29381728 12 Nov 16:44 /usr/bin/clang*
# this is the local install timestamp

$ clang --version
Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
Target: x86_64-apple-darwin12.5.0
Thread model: posix

Compile gets past point of failure.

So is 
  APPLE_CLANG_MINIMUM_VERSION = StrictVersion('4.0')
at http://mxr.mozilla.org/mozilla-central/source/python/mozboot/mozboot/osx.py#34 out of date since some change in js ?

If the tree can't build with Apple Clang 4.0, then perhaps we should up APPLE_CLANG_MINIMUM_VERSION to 4.2 to coincide with LLVM 3.2. Want to create a patch?

I don't have 4.2 on hand to verify that, but sure.
