2 test failures on Mac OS 10.6

[Ben Abbott]

I'm seeing two test failures on Mac OS 10.6. The first error is ...

>>>>> processing 
>>>>> /Users/bpabbott/Development/mercurial/local_clone/src/mappers.cc
  ***** assert (erf (erfinv ([-0.999 -0.99 0.9999 0.99999])), [-0.999 -0.99 
0.9999 0.99999], 1e-16)
!!!!! test failed
assert (erf (erfinv ([-0.999, -0.99, 0.9999, 0.99999])),[-0.999, -0.99, 0.9999, 
0.99999],1e-16) expected
  -0.99900  -0.99000   0.99990   0.99999
but got
  -0.99900  -0.99000   0.99990   0.99999
maximum absolute error 1.11022e-16 exceeds tolerance 1e-16

The actual error is equal to eps/2. Any reason not to increase the tolerance to 
eps?

I couldn't duplicate the 2nd error form the command line.

>>>>> processing test_system
  ***** testif HAVE_GETPWUID
 x = getpwuid (getuid ());
 assert((strcmp (x.dir, tilde_expand ("~"))
 && strcmp (x.dir, tilde_expand (sprintf ("~%s", x.name)))
 && strcmp ("foobar", tilde_expand ("foobar"))));
!!!!! test failed
assert ((strcmp (x.dir, tilde_expand ("~")) && strcmp (x.dir, tilde_expand 
(sprintf ("~%s", x.name))) && strcmp ("foobar", tilde_expand ("foobar")))) 
failed

octave:1> x = getpwuid (getuid ())
x =

  name = bpabbott
  passwd = ********
  uid =  501
  gid =  501
  gecos = Ben Abbott
  dir = /Users/bpabbott
  shell = /bin/bash
}

octave:2> strcmp (x.dir, tilde_expand ("~"))
ans =  1
octave:3> strcmp (x.dir, tilde_expand (sprintf ("~%s", x.name)))
ans =  1
octave:4> strcmp ("foobar", tilde_expand ("foobar"))
ans =  1
octave:5> assert ((strcmp (x.dir, tilde_expand ("~")) && strcmp (x.dir, 
tilde_expand (sprintf ("~%s", x.name))) && strcmp ("foobar", tilde_expand 
("foobar"))))
octave:7> (strcmp (x.dir, tilde_expand ("~")) && strcmp (x.dir, tilde_expand 
(sprintf ("~%s", x.name))) && strcmp ("foobar", tilde_expand ("foobar")))
ans =  1

When I tried to run the test from the command line ...

octave:6> test test_system
  ***** test
 pause (0);
 printf_assert ("ok\n");
 assert(prog_output_assert("ok"));
!!!!! test failed
`printf_assert' undefined near line 4 column 2

The error occurs before the test that failed during "make check". I don't see 
printf_assert in the sources. Can someone illuminate me as to where it is?
