I am tempted to write a macro with an interface like this,

CHECK_INCLUDES( FILES sys/types.h netinet.h VARIABLE HAVE_NETINET_TCP_H)

I suspect that might be better (for me anyhow) ... Thoughts?   it
looks like the list passed in to check_include_files is getting
exploded in to three arguments.

TIA,
George.
