  Portability problems fixed by Gnulib:
  @itemize
  @item
  This function is missing on some platforms:
  HP-UX 11.23, IRIX 6.5, Solaris 9, mingw, MSVC 14.
  @item
  On some platforms, this function does not fail with @samp{EINVAL} when
  passed an empty string or a string containing @samp{=}:
  Mac OS X 10.5, FreeBSD 6.0, NetBSD 1.6, OpenBSD 6.7, Cygwin 1.5.x.
  @item
  On some platforms, this function removes a leading @samp{=} from the
  value argument:
  Cygwin 1.5.x.
  @end itemize
  
  Portability problems not fixed by Gnulib:
  @itemize
  @item
  Older versions of POSIX required that @code{setenv(NULL,"",0)} gracefully
  fail with @code{EINVAL}, but not all implementations guarantee this,
  and the requirement was removed.
  @end itemize
