[Dev-C++] dev C++ producing errors on compiling 'hello world' test;

[Tom H <to...@sc...>]

Hello list,

A quick question;

I downloaded a copy of dev-C++ and opened up the hello world example. It =
looked OK
to me so I did a compile and run without changing anything. But there =
were some compiler
errors which prevented it from finishing.

Any idea what I have done to screw up these include files?
(I've posted the compiler output below;)

Cheers

T.
