Sun Workshop 5.0 works very well, but only after you install all the
available patches. For those who use this compiler, Sun has a useful 
web page,  http://access1.sun.com/forte/, that lets you browse and 
download the patches for all its development tools. Should be the 
first stop after installing any of Sun's dev products.

I doubt if there's a large'ish C++ package in existence that will build
under a stricly comforming C++ compiler (which for example will not
support the backward compatibility thingies that we are so used to).
Octave as of recently is quite close, and it's down to using just one
extension -- use of a non-standard std::filebuf constructor in 
src/c-file-buf-ptr.h -- that is supported by libstdc++-v3 (upcoming 
GNU C++ standard library), and Sun Workshop and a variety of other
good C++ implementations.

I'll submit the patches for Sun Forte series (v6 update 1) sometime 
soon.

If you have lots of C++ code, and want a really good scare, get the 
latest pre-release (or perhaps it's released by now) IBM VisualAge 
C++ and do a build. Lots of fun to watch the compiler go bananas and 
start screaming when it's somebody else's code.

Mumit
