  Gnulib module: snprintf or snprintf-posix
  
  Portability problems fixed by either Gnulib module @code{snprintf} or @code{snprintf-posix}:
  @itemize
  @item
  This function is missing on some platforms:
  IRIX 5.3, OSF/1 4.0, Solaris 2.5.1.
  @item
  This function overwrites memory even when a size argument of 1 is passed on some
  platforms:
  Linux libc5.

  Portability problems fixed by Gnulib module @code{snprintf-posix}:
  @itemize
  @item
  This function does not support size specifiers as in C99 (@code{hh}, @code{ll},
  @code{j}, @code{t}, @code{z}) on some platforms:
  AIX 5.1, HP-UX 11.23, IRIX 6.5, OSF/1 5.1, Solaris 9, Cygwin 1.5.24, mingw, BeOS.
  @item
  printf of @samp{long double} numbers is unsupported on some platforms:
  mingw, BeOS.
  @item
  printf @code{"%f"}, @code{"%e"}, @code{"%g"} of Infinity and NaN yields an
  incorrect result on some platforms:
  AIX 5.2, OSF/1 5.1, Solaris 10, mingw.
  @item
  This function does not support the @samp{a} and @samp{A} directives on some
  platforms:
  glibc-2.3.6, MacOS X 10.3, NetBSD 3.0, OpenBSD 4.0, AIX 5.2, HP-UX 11,
  IRIX 6.5, OSF/1 5.1, Solaris 10, Cygwin 1.5.x, mingw, BeOS.
  @item
  This function does not support the @samp{F} directive on some platforms:
  NetBSD 3.0, AIX 5.1, HP-UX 11.23, IRIX 6.5, OSF/1 5.1, Solaris 9,
  Cygwin 1.5.x, mingw, BeOS.
  @item
  This function does not support the @samp{ls} directive on some platforms:
  OpenBSD 4.0, IRIX 6.5, Solaris 2.6, Cygwin 1.5.x, Haiku.
  @item
  This function does not support precisions in the @samp{ls} directive correctly
  on some platforms:
  Solaris 10.
  @item
  This function does not support format directives that access arguments in an
  arbitrary order, such as @code{"%2$s"}, on some platforms:
  NetBSD 3.0, mingw, BeOS.
  @item
  This function doesn't support the @code{'} flag on some platforms:
  NetBSD 3.0, Cygwin 1.5.24, mingw.
  @item
  This function behaves incorrectly when a @samp{-} flag and a negative width
  are specified together, on some platforms:
  HP-UX 10.20.
  @item
  printf @code{"%010f"} of NaN and Infinity yields an incorrect result (padded
  with zeroes) on some platforms:
  MacOS X 10.3, FreeBSD 6.0, NetBSD 3.0, AIX 5.2, IRIX 6.5, OSF/1 5.1, Solaris 10, Cygwin 1.5.x, mingw.
  @item
  This function does not support precisions larger than 512 or 1024 in integer,
  floating-point and pointer output on some platforms:
  mingw, BeOS.
  @item
  This function can crash in out-of-memory conditions on some platforms:
  MacOS X 10.3, FreeBSD 6.0, NetBSD 3.0.
  @item
  This function does not truncate the result as specified in C99 on some platforms:
  mingw.
  @item
  This function does not return a byte count as specified in C99 on some platforms:
  HP-UX 11, IRIX 6.5, OSF/1 5.1, mingw.
  @item
  This function does not fully support the @samp{n} directive on some platforms:
  HP-UX 11, mingw.
  @item
  This function overwrites memory when a size = 1 argument is passed on some
  platforms:
  BeOS.
  @item
  This function overwrites memory even when a zero size argument is passed on some
  platforms:
  OSF/1 5.1.
