Clang: Removed option no more supported.
Some hidden loads for pywin32
Windows: Turn warnings into errors in debug mode for MSVC too.
"Cish", major refactoring

* Use less C++ classes, and generate more C-like code. Temporary variables
  are now used, where previously everything in a statement was wrapped in
  C++ temporary objects.

* Exception handling is now pure C code, no more "throw" at all. That means
  return codes are checked. This gives a huge performance increase for the
  use of Python exceptions.

* Generation of tuples and lists is now done without helper functions, these
  were only increasing code complexity.

* Access to local and global variables with more direct code.

* Less use of templates, more code is manually crafted.

* Moved publishing and preservation of exceptions to node tree.

* Enhanced handling of try/except and try/finally for Python3 by doing
  reformulations for their handler semantics.

* Exception handling as now done via branching.

  Huge simplification for SSA, as exception catching is now explicit
  via normal branch analysis, removing handlers as special cases.

* Many asorted improvements.

* Many, many cleanups.
Windows: Detect download errors case for depends.exe, improved debug output.

* This corrects Issue#129
Added support for comparing outputs with "python-dbg"

* Parsing refcount reports and make sure they are equally static.

* This enables more reference count coverage, coming from th CPython
  test suites.
Added support for "venv" of Python3.3, which has no include or libs.
Python2: Fix, do not convert source to unicode with ASCII encoding
Standalone: Cleanups
Fix, modules with name "builtin" were conflicting with internal identifiers.
Fix, modules with "(" and ")" in their names were not working.
Temporary avoid modules with "(" in their names.
Updated to new version of GUI
Standalone: Added "idna" encoding.
Standalone MacOS: Remove unsupported option for linking.
Debian: Drop unnecessary build-depends for C++ compiler

* It's already required by build-essential, and the oldest supported
  Ubuntu system is bigger than 4.6.0 already, so it's no more necessary.

* Also added g++ 4.9 as allowed C++ compiler, which is now in Jessie.
Windows: Be more robust about deleting executed binaries.
MacOS Standalone: Added support for detecting DLLs on MacOS.
virtualenv: Some virtualenv have ".Python" links to find the original install.

* At least on MacOS X, these have been found, and are necessary to handle
  "Homebrew" installs that are newer than the system installation.

* Might apply to other platforms as well.
New pre-release.
