Portability problems not fixed by Gnulib:

  * This function should never be used, because it can overflow any given buffer.

  * When reading from a non-blocking pipe whose buffer is empty, this function fails with errno being set to EINVAL instead of EAGAIN on some platforms: mingw, MSVC 9.

  * On Windows platforms (excluding Cygwin), this function does not set errno upon failure.
