When compiling installwatch from ports, the following warnings appear:
installwatch.c: In function `open':
installwatch.c:577: warning: `mode_t' is promoted to `int' when passed through `...'
installwatch.c:577: warning: (so you should pass `int' not `mode_t' to `va_arg')
installwatch.c:577: note: if this code is reached, the program will abort

The threat made by gcc on the last line is not an empty one.  When using
installwatch, it will exit with a bus error.

Fix: There's probably a better way to fix this, but as mode is defined as an int
in vfs_syscalls.c, I figured I'd just duplicate it here.  It quickly alleviated
the issue on my end.
