New submission from STINNER Victor <vstinner at python.org>:

I would like to change Py_FrozenMain() using the new PyConfig C API, but I would prefer to first write tests of its current behavior. Currently, Py_FrozenMain() has no test.

Py_FrozenMain() is used by Tools/freeze/freeze.py. Old freeze.py issues:

* bpo-42613: freeze.py doesn't support sys.platlibdir different than lib nor multiarch
* bpo-40954: freeze.py aborts on macOS
* bpo-32217: freeze.py fails to work.
* bpo-27727: Update Tools/freeze to use .vcxproj files 
* bpo-27566: Tools/freeze/winmakemakefile.py clean target should use 'del' instead of 'rm' 
* bpo-26271: freeze.py makefile uses the wrong flags variables
* bpo-25504: undefined name 'modules' in Tools/freeze/checkextensions_win32.py 
* bpo-24871: freeze.py doesn't work on x86_64 Linux out of the box
* bpo-23405: Tools/freeze "make" gets missing file error with unix shared builds 
* bpo-21502: freeze.py not working properly with OS X framework builds
* bpo-16047: Tools/freeze no longer works in Python 3
* bpo-11824: freeze.py broken due to ABI flags
* bpo-7517: freeze.py not ported to python3
* bpo-6078: freeze.py doesn't work 
* bpo-1985: Bug/Patch: Problem with xml/__init__.py when using freeze.py 
* bpo-588452: $DEBUG_PYTHON -O freeze.py broken 

I never used freeze.py, but since we get bug reports, it seems like it's used by users :-)

Note: freeze.py has no test neither.
