Do not compile Lexicon.py. It's really only used once and is much larger as a binary module than as a byte code file, but not slower to import.

Include deprecation warning from CPython (3.3+) in __Pyx_PyNumber_IntOrLong() and avoid inlining error handling code.

Streamline __Pyx_PyNumber_IntOrLong() with direct slot calls instead of C-API function calls that only do what we already do on our side already.

Specialise coercion from bytes to char* (and friends) to avoid going through several type checks in the generic "__Pyx_PyObject_AsStringAndSize()" function.

Split uncommon case from unicode/bytes.endswith() implementation to suggest inlining the normal case.

Fix reference leak in the Py2.x __Pyx_ReleaseBuffer() implementation for types with an overridden __releasebuffer__ method.

Closes #1638.

Fix more tests: Correct the source character position of name nodes to improve error reporting (previously reported the character position *behind* the name).

Correct the source character position of name nodes to improve error reporting (previously reported the character position *behind* the name).

Closes #1824.

Repair "range(enum)" iteration in C++ which (rightfully) disallows arbitrary assignments between enum+int.

Revert "Re-enable failure checks for Py3.2 in travis as that version is correctly supported (again)."

This reverts commit 835cf4c1.

The travis test runs seem to be unreliable for some reason.
