glibc 2.9 "make check" fails on rt/tst-cputimer with "timersig[12] invoked too soon"


I wish to install a new libc.so and have compiled the latest glibc
(2.9.90) with the latest gcc (4.3.3) and the latest binutils (2.19,
compiled with gcc 4.3.3).  The "configure" options for gcc, binutils,
and glibc were all identical.

I am running into an error with rt/tst-cputimer that I do not know how
to avert.  I have run 'make check' 3 times; here are the 3 results.
The following is from rt/tst-cputimer1.out:

 clock_gettime returned timespec = { 0, 0 }
 clock_getres returned timespec = { 0, 1 }
 *** timer sig1 invoked too soon: 2.900000000 instead of expected 3.400000000
 *** timer sig2 invoked too soon: 2.900000000 instead of expected 3.900000000

The following is from rt/tst-cputimer2.out:

 clock_gettime returned timespec = { 0, 0 }
 clock_getres returned timespec = { 0, 1 }
 *** timer sig1 invoked too soon: 2.904000000 instead of expected 3.404000000
 *** timer sig2 invoked too soon: 2.904000000 instead of expected 3.904000000

And the following is from rt/tst-cputimer3.out

 clock_gettime returned timespec = { 0, 0 }
 clock_getres returned timespec = { 0, 1 }
 *** timer sig1 invoked too soon: 2.916000000 instead of expected 3.416000000
 *** timer sig2 invoked too soon: 2.916000000 instead of expected 3.916000000

Further information that may or may not be relevant -- here is /proc/cpuinfo:

And here is the output of "uname -a":

 Linux m5 2.6.13-15-default #1 Mon Jul 2 12:49:30 CDT 2007 i686 i686 i386 GNU/Linux

I don't want to install the new libc.so until I can get all the tests
to succeed, or, failing that, until I understand the significance of
the error, and can intelligently dismiss it.  What shall I do?  Thank
you in advance for your replies.
