Quick question, do you plan to expose the C argv values as part of this work?

Issue #14208 asks for the full C argv array; my use-case today required only the C argv[0]. Both of the use-cases had to do with having a script reexecute itself (eg, 'os.execl(sys.executable, *args)').

I don't remember where, but it was already asked how is it possible to recreate the Python command line to create a subprocess with the Python command line options.

For example:

$ python -O -c "import sys; print(sys.argv)" ['-c']

How do you get ['python', '-O']? I guess that the question was for the multiprocessing on Windows (which does not support fork).
