If you're going to post examples, try to make them adhere to standard
programming conventions.  main() must always return an integer.  Also,
gcc can recognize C++ programs with the extensions .C (capital c), .cc,
and .cpp.  And you're omitting the most important part, linking the C++
library.

To correctly compile the above program, you must use one of these two
command lines:

gcc -o hello.exe hello.cpp -lgpp

gxx -o hello.exe hello.cpp

'gxx' takes care of linking the C++ libraries for you.  If you use
RHIDE, you don't need to worry about this as long as you give your
source file a correct name.

If you have further problems, please consult the 'readme.1st' file
and/or the DJGPP Frequently Asked Questions list (v2/faq210b.zip from
SimTel or online at http://www.delorie.com/djgpp/v2faq/).  You won't be
disappointed.
