bug? : g++: `ios::ios(const ios &)' is private

[A Mennucc1 <debian@Tonelli.sns.it>]

hi

if `date -u` is later than Thu Dec 13 20:00:00 UTC 2001 
then please skip this message




we are trying to port some code from Window$ to Debian

I found the below behaviour which may be a bug, and have posted it as
such... but maybe it is not a bug (I am not very good at c++)

may someone give a look?

thanks

a.

hi

I include a piece of code, as first attachment, and the error that I get,
as second attachment

it exemplifies an error that I have already found twice

also, this piece of code compiles ok using Micro$oft Visual c++

I am not good at c++ but I suppose that this code should not
result into that error
