I have this strange (or not) problem whilst compiling C and C++.

Is it still true, that in ANSI C, prototypes are recomended, but not
compulsory,
whilst in C++ they are compulsory?

The problem is that if I use a function such as 'strlen' and do not explicitly
include
the headers file (string.h), it gets included anyway. I know that it is because
I included a conditional compilation construct to test for
'__dj_include_string_h_'.
e.g.
#ifdef __dj_include_string_h_
  cout << "Its included!\n";
#endif

Could some one please explain how the header files are being included in the
compile, or whether I'm just mad?

Thanks.

Mark Matten.
