New submission from STINNER Victor <vstin...@redhat.com>:
The compilation of Modules\zlib\ on Python 2.7 emits a lot of warnings: see AppVeyor logs above. I propose to define _CRT_SECURE_NO_WARNINGS in the pythoncore project to make these warnings quiet, to spot more easily new warnings. Attached PR adds _CRT_SECURE_NO_WARNINGS to Python 2.7 pythoncore project. In the master branch, the following project also set _CRT_SECURE_NO_WARNINGS: * PCbuild/_decimal.vcxproj * PCbuild/_elementtree.vcxproj * PCbuild/_ssl.vcxproj * PCbuild/pyexpat.vcxproj Note: In the master branch, encode_current_locale() of Python/fileutils.c also uses wcstombs(), but no warning is emitted, whereas the C file is compiled by the pythoncore project which doesn't define _CRT_SECURE_NO_WARNINGS.
