No good - I get "no class template named 'iterator' in 'std'" - presumably
because of problems with the g++ non-implementation of the std namespace
(the -fhonor-std flag fails as the mingw libraries aren't built with it).

I tried without the stdio implementation (latest beta STLport) as the
library builds break horribly for me. The stlport seems to want to find the
g++ headers in a directory 'g++' in a path relative to where the stlport was
installed (contrary to the documentation!) - and even if I installed stlport
in the Mingw directories, things like iostream.h are in a directory 'g++-3',
not 'g++'.

Tried that, but got "not configured for this operating system". Looking at
the source, it means what it says - there isn't a setup for gcc/mingw (yet?)

                 from rational_example.cpp:11:
STL\stl_stdio_file.h:163: #error The C++ I/O library is not configured for

Sorry - this is way off-topic, but I'd REALLY like to be able to use
gcc/mingw on Windows as an alternative c++ compiler. But I just can't get it
to work (by "work", I mean providing something like a conforming standard
library). People keep saying that it is possible, but I've never been able
to get it to work. I have the latest mingw snapshot, and I've asked on the
mingw and STLport mailing lists among other places. If *anyone* can give me
a step-by-step description of how to get any of the public C++ standard
libraries working with mingw, I would be eternally grateful.

John, I'll look into, and sort out, your other reports on the rational
library soon.

Thanks,
Paul.
