I'm in the process of setting up ChannelArchiver here and ran into the
same problem. I'm using solaris 7 and gcc 2.95.3.

The clue is in EngineServer.cpp:

	#ifdef solaris
	// silly clash with struct map on Solaris
	// as long as namespaces are not used by egcs C++ library:
	#define _NET_IF_H
	#endif

Why this ifdef isn't working, I wasn't able to determine (solaris is
defined, and /usr/include/net/if.h begins with #ifndef _NET_IF_H). But I
was able to compile by explicitly not including <net/if.h>.

On a somewhat related note, MatlabExporter.cpp, GNUPlotExporter.cpp and
CGIInput.cpp do not compile when using the -ansi flag to gcc. Without it,
they compile fine.
