Let me try and recap.

The initial report was that 5.3 TL10 did *not* have the error.  I discovered
that 5.3 TL10 SP03 does.  See [1].

APAR IZ81343[2] and its sister APARs addresses this issue.  It is shipped (for
example) in 5.3 TL10 SP05 as IZ81339.

After you apply that APAR, you get a new issue where the linker now spews out:

ld: 0711-596 SEVERE ERROR: Object expand.o
        An RLD for section 2 (.data) refers to symbol 852,
        but the storage class of the symbol is not C_EXT or C_HIDEXT.

I got this when I tried to build GNU's make on 5.3 TL10 SP02 with just the
assembler APAR.  I tried two versions of GCC: 4.2.0 and 4.5.2.

IBM is aware of the issue (via me and others).  The last tidbit I have is that
it appears as if it is another assembler bug but that is not confirmed yet.  I
don't have a fix nor do I have an APAR number yet.
