Gnulib module: extensions

Portability problems fixed by Gnulib:

• This function has an incompatible declaration on some platforms: Solaris 11.4 (when _POSIX_PTHREAD_SEMANTICS is not defined).

Portability problems not fixed by Gnulib:

• This function is missing on some platforms: mingw, MSVC 14.
• This function is removed in POSIX.1-2024. Use the functions localtime_r and strftime (or even sprintf) instead. However, localtime_r can fail and strftime is locale dependent.
• This function may overflow its output buffer if its argument specifies a time before the year 1000 or after the year 9999. See ctime.
• This function may dereference an internal null pointer if its argument specifies a time before the year INT_MIN+1900 or after the year INT_MAX+1900.
