Use "Py_ssize_t" instead of "int" for a node counter variable to avoid uselessly limiting its value range.

Adapt to "exc_info" changes in CPython 3.11a4, where "->exc_type" and "->exc_traceback" are gone and now get inferred from "->exc_value".

Cython incorrectly generated (optimised) range code for "for i in range(1,2,3,4)" as if it saw "for i in range(1,2,3)".
This PR deactivates this optimization when too many arguments are provided, to match the behavior of Python.

Remove outdated warning about OpenMP < 3.0. Even the now-EOL Docker images for manylinux2010 had that.

Make the test files that depend on "cythonarrayutil.pxi" compilable by themselves, without the search directory setup of the test runner.

Disable the "dotted names not allowed" warning for include files, which may contain arbitrary directory paths and not just plain module names.

Add a new command line option so that
$ cythonize -M foo.pyx
produces a file `foo.c.dep` with dependencies of foo.pyx, in addition to `foo.c`.
Try to write relative paths as much as possible.

Avoid misleading the C code formatter into adding an additional indentation level due to excess opening braces.

Make it easier to report errors from srctree tests by adding the last output to the reported AssertionError.

appveyor: Prevent the compiled Cython modules from being picked up during the build already by first compiling them completely before putting them into the source tree. On fork()-less Windows, late starting build processes could otherwise end up with partially compiled source trees.

Make the pyximport-pyimport tests more robust by testing that the file is compiled instead of looking at the "__file__" attribute.

Add missing import in doctest when the module is compiled (and StringIO has become a global cdef variable).
