After compiling glibc-2.10.1, make tests return errors.

Hi,

I just compiled glibc-2.10.1 natively for an i686 Q6600 running linux-2.6.29.5 
and gcc-4.2.2.  I am at the point of making the tests.

I configure as follows.  The straightforward configure leads to an error later 
at compile time:

  undefined reference to `__sync_fetch_and_add_4

The following configure command allows me to compile without errors.

  CFLAGS="-march=i686 -mtune=generic -O3" ../glibc-2.10.1/configure 
--prefix=/usr --with-headers=/sa107/wa_rlx/linux-2.6.29.5/usr/include 
--disable-profile          --enable-add-ons --enable-kernel=2.6.0 
--libexecdir=/usr/lib/glibc

However the tests return errors.  Are those to be expected?  This is not the 
first time I compile glibc but I feel a bit anxious every time I need to install 
a new one.

First error occurs in the math library: math/test-double.out

testing double (without inline functions)
Failure: Real part of: cacosh (0 - 0 i) == 0.0 - pi/2 i: Exception "Invalid 
operation" set
Failure: Real part of: cacosh (inf - inf i) == inf - pi/4 i: Exception "Invalid 
operation" set
Failure: Real part of: cacosh (0 + inf i) == inf + pi/2 i: Exception "Invalid 
operation" set

Test suite completed:
  3041 test cases plus 2641 tests for exception flags executed.
  3 errors occurred.

Then doing 'make check' again, I get,

make[2]: *** [/sa107/wa_rlx/build_glibc/nptl/tst-mutex5.out] Error 1

running the above command manually returns

  Timed out: killed the child process

I can't make the other checks.  Is glibc-2.10.1 supposed to be stable
and if not which one is?

Thanks

Richard
