Misc fixes for Windows. Most of these changes have to do with how python scripts are invoked. For Linux, 'Popen([EMCC] + args)' works because the first line in emcc is '#!/usr/bin/env python'. On Windows, the python interpreter has to be explicitly invoked, e.g. 'Popen(['python', EMCC] + args)'. Note that there is no harm in explicitly invoking the python interpreter on Linux, so this works on both platforms. For Windows, execvp() behaves differently than on Linux: http://mail.python.org/pipermail/python-list/2002-July/763863.html http://msdn.microsoft.com/en-us/library/3xw6zy53.aspx This causes many strange things to happen as the parent process terminated before its children. In this change the use of execvp() has been replaced with subprocess.call(). This change also fixes some code that assumed that the path separator always is '/', but for Windows it is '\'. And where the path module can be required, we use path.normalize() and path.resolve() to check if a filename is absolute in a platform agnostic manner. 2012-03-20 17:26:50 +04:00			`import os, subprocess, sys`

Use llvm-ar instead of llvm-link in emar This makes the semantics of emar to be the same as the semantics of system ar. 2012-02-08 02:05:22 +04:00			`newargs = [shared.LLVM_AR] + sys.argv[1:]`
