  Gnulib module: fprintf-posix or stdio, nonblocking, sigpipe
  
  Portability problems fixed by Gnulib module @code{fprintf-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, Solaris 9, Cygwin 1.5.24, mingw, MSVC 14.
  @item
  printf of @samp{long double} numbers is unsupported on some platforms:
  mingw, MSVC 14.
  @item
  printf @code{"%f"}, @code{"%e"}, @code{"%g"} of Infinity and NaN yields an
  incorrect result on some platforms:
  AIX 5.2, Solaris 11.4, mingw, MSVC 14.
  @item
  This function does not support the @samp{a} and @samp{A} directives on some
  platforms:
  glibc-2.3.6, Mac OS X 10.5, NetBSD 9.0, OpenBSD 4.0, AIX 5.2, HP-UX 11,
  IRIX 6.5, Solaris 11.4, Cygwin 1.5.x, mingw, MSVC 14.
  @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, Solaris 9,
  Cygwin 1.5.x, mingw, MSVC 14.
  @item
  This function does not support the @samp{n} directive on some platforms:
  glibc when used with @code{_FORTIFY_SOURCE >= 2} (set by default on Ubuntu),
  macOS 11.1, MSVC 14.
  @item
  This function does not support the @samp{ls} directive on some platforms:
  OpenBSD 4.0, IRIX 6.5, Cygwin 1.5.x, Haiku.
  @item
  This function does not support precisions in the @samp{ls} directive correctly
  on some platforms:
  Solaris 11.4.
  @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, MSVC 14.
  @item
  This function doesn't support the @code{'} flag on some platforms:
  NetBSD 3.0, Cygwin 1.5.24, mingw, MSVC 14.
  @item
  This function does not round the argument of the @samp{a} directive correctly
  on some platforms:
  Mac OS X 10.12, FreeBSD 13.0.
  @item
  printf @code{"%010f"} of NaN and Infinity yields an incorrect result (padded
  with zeroes, or wrong capitalization) on some platforms:
  Mac OS X 10.5, FreeBSD 6.0, NetBSD 5.0, AIX 5.2, IRIX 6.5, Solaris 11.4, Cygwin 1.5.x, mingw, MSVC/clang.
  @item
  This function does not support precisions larger than 512 or 1024 in integer,
  floating-point and pointer output on some platforms:
  AIX 7.1, Solaris 10/x86, mingw, MSVC/clang.
  @item
  This function mishandles large floating point precisions
  (for example, formatting 1.0 with @samp{"%.511f"})
  on some platforms:
  Solaris 10.
  @item
  This function can crash in out-of-memory conditions on some platforms:
  FreeBSD 13.0, NetBSD 5.0.
  @end itemize
  
  Portability problems fixed by Gnulib module @code{stdio} or @code{fprintf-posix}, together with module @code{nonblocking}:
  @itemize
  @item
  When writing to a non-blocking pipe whose buffer is full, this function fails
  with @code{errno} being set to @code{ENOSPC} instead of @code{EAGAIN} on some
  platforms:
  mingw, MSVC 14.
  @end itemize
  
  Portability problems fixed by Gnulib module @code{stdio} or @code{fprintf-posix}, together with module @code{sigpipe}:
  @itemize
  @item
  When writing to a pipe with no readers, this function fails, instead of
  obeying the current @code{SIGPIPE} handler, on some platforms:
  mingw, MSVC 14.
  @end itemize
  
  Portability problems not fixed by Gnulib:
  @itemize
  @item
  The @code{%m} directive is not portable, use @code{%s} mapped to an
  argument of @code{strerror(errno)} (or a version of @code{strerror_r})
  instead.
  @item
  Formatting noncanonical @samp{long double} numbers produces
  nonmeaningful results on some platforms:
  glibc and others, on x86, x86_64, IA-64 CPUs.
  @item
  When formatting an integer with grouping flag, this function inserts thousands
  separators even in the "C" locale on some platforms:
  NetBSD 5.1.
  @item
  Attempting to write to a read-only stream fails with @code{EOF} but
  does not set the error flag for @code{ferror} on some platforms:
  glibc 2.13, cygwin 1.7.9.
  @end itemize
