[New-bugs-announce] [issue19569] Use __attribute__((deprecated)) to warn usage of deprecated functions and macros

[STINNER Victor]

New submission from STINNER Victor:

Python C API evolves. For example, the Unicode type has been rewriten for scratch to use a more efficient design. Would it be possible to mark deprecated functions as deprecated, so users will be noticed that the API evolved and Python has better functions?

For example, PyUnicode_GET_SIZE() is deprecated and returns a different value than PyUnicode_GET_LENGTH() if wchar_t size is 16-bit (ex: Windows and AIX).

GCC has an nice __attribute__((deprecated)) to tag functions.
