* src/stdstreams.cc: Initialize with NULL filebuf. Delete
|

initialization routines into one file to simplify DSO interaction.
|

* include/bits/std_iostream.h: Touch.
|
||||
* include/bits/ios_base.h (_S_synched_with_stdio): Make static.
|

* src/Makefile.am (sources): Remove stdstreams.cc.
|

* src/Makefile.in: Regenerate.
