[New-bugs-announce] [issue36020] HAVE_SNPRINTF and MSVC std::snprintf support

[palotasb-conti]

New submission from palotasb-conti <boldizsar.palotas at continental-corporation.com>:

Abstract: pyerrors.h defines snprintf as a macro on MSVC even on versions of MSVC where this workaround causes bugs.

snprintf is defined as _snprintf in pyerrors.h, see: https://github.com/python/cpython/blob/ac28147e78c45a6217d348ce90ca5281d91f676f/Include/pyerrors.h#L326-L330

The conditions for this should exclude _MSC_VER >= 1900 where (std::)snprintf is correctly defined. Since this is not the case, subsequent user code that tries to use std::snprintf will fail with an err (_snprintf is not a member of namespace std).
