The use of <iostream> (name of header without '.h' extension) is a
relatively new C++ feature that is not supported by gcc 2.7.2.1, the
version you probably still have.  It's quite shiny-new, in fact, so many
compilers probably still don't support it.

Fortunately, the latest version of gcc, 2.8.0, has been recently ported
to DJGPP, and it contains far better C++ support than the previous
version (although exceptions are semi-broken).  If you decide to
download it, you should completely replace your old 2.7.2.1 files; i.e.,
delete them completely and then install 2.8.0 from scratch.  The files
are gcc280b.zip, gpp280b.zip, and lgpp280b.zip.  If you are running
under Windows 95, you will probably want to change the registry
according to FAQ chapter 8.2 to make it LFN/SFN-clean, and you'll need
to make a small fix to RHIDE.

If you'd rather stick with 2.7.2.1, change <iostream> to <iostream.h>,
the way God intended it to be.  :-)
