            Bug ID: 2961
           Summary: session.c:523: error: too few arguments to function
                    ‘session_set_fds’ when USE_PIPES is not defined
           Product: Portable OpenSSH
           Version: 7.9p1
          Hardware: Other
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P5

Hi. I'm encountering the following compilation error when I empty the
line with "#define USE_PIPES 1":

session.c: In function ‘do_exec_no_pty’:
session.c:523: warning: passing argument 1 of ‘session_set_fds’ from
incompatible pointer type
session.c:116: note: expected ‘struct ssh *’ but argument is of type
‘struct Session *’
session.c:523: warning: passing argument 2 of ‘session_set_fds’ makes
pointer from integer without a cast
session.c:116: note: expected ‘struct Session *’ but argument is of
type ‘int’
session.c:523: error: too few arguments to function ‘session_set_fds’

The following patch fixes it:

$ diff -ur openssh-7.7p1-orig openssh-7.7p1-fixed
diff -ur openssh-7.7p1-orig/session.c openssh-7.7p1-fixed/session.c

I don't get the compilation error when I don't remove "#define
