Problem including certain C header files in C++ programs (net/if. h and sys/stat.h in particular)

[Dave Gotwisner]

I am trying to build a C++ program (using G++) that includes both net/if.h
and sys/stat.h.  When I compile my program,
I get several warnings which report as many lines of includes plus the
warning.  I would like to be able to turn off the
warnings around the header files (I assume this is with a #pragma).
I want to keep a fairly high level of warnings enabled under normal use.  Is
there a way to do what I want?

The compiler options being used (for warnings) are: -Wall -Wshadow -ansi.

The warning received for net/if.h is: warning: `int ifconf (int, char *)'
hides constructor for `struct ifconf'.

Looking at the header file, the structure is defined as:

struct ifconf {
	int ifc_len;
	...
};

and the line that causes the problem is:

	extern int ifconf(int, caddr_t);

The code is correctly contained in extern "C" {...} for the C++.

The platform/target being used here is Sparc-Solaris8 / VxWorks-simulator
(or VxWorks-mips).  These structures look consistent with what
I am used to for Linux / BSD, so I doubt it is a VxWorks-ism (and their
support for C++ is poor to be polite).

My understanding of the way C++ works is that a constructor for a class
ifconf should be declared ifconf::ifconf(), NOT ifconf(), so I don't really
see why this is even being reported.

Compiler versions used 2.96 for the simulator and for mips.

Thanks in advance,
