Re: bug compiling libstdc++ under solaris

[baron at peanut dot engr dot sgi dot com (Baron Roberts)]

I don't have a Sun handy but one interesting data point is that RedHat
Linux does not provide a getwchar function or macro. So this would
explain why I did not hit this problem when building egcs on Linux.

Another interesting data point is that my patch did not include anything
that would trigger a call to getwchar. Perhaps I am misunderstanding your
question. Is this just something else that came up when trying to get
the wchar_t support working rather than a problem with the patch I sent?
In any case I am not sure where the call to getwchar is coming from.

If I can get hold of a Sun (not too many at SGI :-)) I will try to reproduce
this.

By the way, I sent another patch this morning to fix the operator<<
in bastring.cc. The call to the write method must use

	s.length() * sizeof(charT)

instead of just s.length() when specifying the stream size. The way
it is now will work for char* but not for wchar_t*.

Sorry I cannot be of more direct help.
