  Gnulib module: perror
  
  Portability problems fixed by Gnulib:
  @itemize
  @item
  This function does not support the error values that are specified by POSIX
  but not defined by the system, on some platforms:
  OpenBSD 4.0, Cygwin 1.5.x, mingw, MSVC 14.
  @item
  This function treats @code{errno} of 0 like failure, although POSIX
  requires that the message declare it as a success, on some platforms:
  FreeBSD 8.2, OpenBSD 4.7, macOS 11.1.
  @item
  This function clobbers the @code{strerror} buffer on some platforms:
  Cygwin 1.7.9.
  @item
  This function fails to print a useful a string for out-of-range integers on
  some platforms:
  HP-UX 11, IRIX 6.5.
  @end itemize
  
  Portability problems not fixed by Gnulib:
  @itemize
  @item
  POSIX requires that this function set the stream error bit (detected
  by @code{ferror}) on write failure, but not all platforms do this:
  glibc 2.13, cygwin 1.7.9.
  @item
  POSIX requires that this function not alter stream orientation, but
  the gnulib replacement locks in byte orientation and fails on wide
  character streams.
  @end itemize
