Thanks... I have replaced 
#include <sys/vfs.h>

with 

#include <sys/mount.h>
#include <sys/param.h>

Now when trying to build the program, I get the following error :

gcc -g -g3 -O2 spacewatcher.c -o spacewatcher
In file included from /usr/include/sys/mount.h:40,
                 from spacewatcher.c:13:
/usr/include/sys/ucred.h:47: syntax error before `u_short'
/usr/include/sys/ucred.h:50: syntax error before `gid_t'
spacewatcher.c: In function `build_alert':
spacewatcher.c:112: warning: initialization makes pointer from integer without a cast
*** Error code 1

It loks like it doesn't like u_short and gid_t ... The section from
ucred.h is as follows :

struct ucred {
    u_short cr_ref;         /* reference count */
    uid_t   cr_uid;         /* effective user id */
    short   cr_ngroups;     /* number of groups */
    gid_t   cr_groups[NGROUPS]; /* groups */
    struct  uidinfo *cr_uidinfo;    /* per uid resource consumption */
};

I have written a mostly empty c file called test.c that just looks
like 

#include <stdio.h>
#include <sys/mount.h>
#include <sys/param.h>

void main (void) {

}

It still produces the same error. Is there another header file I need
to include for this to work ?

Thanks in advance ...
