 The relevant caveat here is the one described in the COMPATIBILITY
 section of the manpage:
 
 COMPATIBILITY
      Many application writers used the name getline before the getline() func-
      tion was introduced in IEEE Std 1003.1 ("POSIX.1"), so a prototype is not
      provided by default in order to avoid compatibility problems.  Applica-
      tions that wish to use the getline() function described herein should
      either request a strict IEEE Std 1003.1-2008 ("POSIX.1") environment by
      defining the macro _POSIX_C_SOURCE to the value 200809 or greater, or by
      defining the macro _WITH_GETLINE, prior to the inclusion of <stdio.h>.
      For compatibility with GNU libc, defining either _BSD_SOURCE or
      _GNU_SOURCE prior to the inclusion of <stdio.h> will also make getline()
      available.
