Portability problems fixed by Gnulib:

Portability problems not fixed by Gnulib:

  * This function should never be used, because it can overflow any given buffer.

  * This function is missing on some platforms: OpenBSD 6.7, Solaris 11.4.

  * POSIX says this function is obsolescent and it is planned to be removed in POSIX 202x. Use the function fgets instead.

  * When reading from a non-blocking pipe whose buffer is empty, this function fails with errno being set to EINVAL instead of EAGAIN on some platforms: mingw, MSVC 14.

  * On Windows platforms (excluding Cygwin), this function does not set errno upon failure.
