today's changes


I've checked in quite a lot of changes today.  Most of them prevent
crashes in case somebody uses a stream (mostly stderr) with a wide
char function and then calls a library using the same stream.
Fortunately the use of wide char streams seems not yet to be wide
spread.  The actual code is pretty ugly.  Since all of the affected
functions (or at least the part of the code affected) is not
frequently used I've opted for a solution which is not producing too
much code at the cost of being slower.

The other work is something I failed to do before the release: avoid
calling functions by more than one name.  The reduces the PLT size.


Anyway, beside some more warnings due to missing declarations etc I
expect no problems.
