[Bug libstdc++/13731] New: [3.4/3.5 regression] Low level I/O not safe wrt short writes

[paolo at gcc dot gnu dot org]

This issue must be fixed before the release of 3.4.0,

  http://gcc.gnu.org/ml/libstdc++/2003-07/msg00212.html,

particularly relevant for pipes.

It's a regression, because 3_3-branch uses fwrite.
