John is very right about this. There is a problem when you use net/
within an include statement. The following code compiles: !!!

---------------------------------------------------------------------------
$ type nettest.c
#include <stdio.h>
#include <net/does_not_exist.h>

int main(int argc, char *argv[])
        {
        printf("Testing net include\n");
        return 0;
        }
$ cc nettest.c
---------------------------------------------------------------------------

Change this to the following and you get the expected error:

---------------------------------------------------------------------------
$ type nettest.c
#include <stdio.h>
#include <net1/does_not_exist.h>

int main(int argc, char *argv[])
        {
        printf("Testing net include\n");
        return 0;
        }
$ cc nettest.c

#include <net1/does_not_exist.h>
.^
%CC-F-NOINCLFILEF, Cannot find file <net1/does_not_exist.h> specified in #includ
e directive.
---------------------------------------------------------------------------

$ cc/version
VSI C V7.4-002 on OpenVMS Alpha V8.4-2L2
