Sorry to say, but you're wrong. The headers and classes you detected were
part of the ANSI-C++ 2.0 spec, the others are part of ANSI-C++ 3.0 and
should be there.

limits: it is known that it is missing
sstream: new IO classes are in development and hopefully ready soon

Try www.STLport.org

 I might not be the right person to comment on this.

 First of all I don't know if I understand your
terminology. g++ could eather be the C++ compiler.
Or the libg++ library. libg++ is an old library and
is not used anymore. When you compile C++ programs
with g++/gcc today you use libstdc++. And neather
g++/gcc or the libstd++ is up to date. v3 of both is
in development. Don't know the state at the moment.
I guess maybe one of the g++/gcc maintainers could
comment on it. libstdc++ is not realy a part of
g++/gcc. It is developed in another team.

Books aren't the best sources to get the latest standard.  I haven't been
following g++ or C++ in a while so I can't comment on how conformant g++ is, but
I would look through the web to find the latest standard.  The latest one I have
is dated 2 December 1996.

G++ and ISO C++ conformity?

[christoph.loewe]

Hi,

I have recently downloaded the latest Cygwin archive
to start a project in C++. I have read Bjarne Stroustrup's
"The C++ Programming Language" (Special Ed.) and was surprised
to find several includes and functions missing in the g++
distribution.

Header files that could not be found:
     <limits>   e.g. numeric_limits<int>::max();
        <sstream>  e.g. ostringstream ost;

Furthermore the "range controlled" indexing via at()
would not work.

Can it be that G++ does not completely support ISO C++?
Or did I forget to install something?
Is an update planned, if indeed some features of ISO C++
are indeed missing in g++?

I used the Setup.exe and did a complete Install via
Internet.

Thanks for your time...

Regards,
     AEon

I just started using C++ myself, so I can't answer all your questions, but
what I can say is that the stringstream stuff is there -- it's just named
differently.  On my Cygwin (1.1.2 base), /usr/include/g++-3/ contains
strstream, not sstream, and the classes it defines are called things like
ostrstream, not ostringstream.  HTH.

Correct me if I am wrong, but haven't string streams been depricated?
