It looks like this is resolved with binutils-2.21.  I used the gld from
binutils-2.21 with the .o files produced by gas in binutils-2.20.1 and the
gcc-4.5.2 compiler, and the tls/static-1.C test now passes.  (Using gcc's -v
feature to find out what the actual link command was; replacing collect2 with a
direct call to ld seems to work well enough for this test.)

I haven't tried x86-64 yet; I'm a bit short of CPU power on that one.

If binutils were in use (which doesn't seem to be the case from the g++
-v output), you'd be right: before my patches that went into binutils
2.21, gld cannot have worked with static TLS on Solaris 2:

    Properly align static TLS segments on Solaris 2

        http://sourceware.org/ml/binutils/2010-10/msg00291.html

    Properly align static TLS segments on Solaris 2/SPARC
        http://sourceware.org/ml/binutils/2010-10/msg00348.html

I'll add a corresponding caveat to the GCC 4.6 installation docs.

On SPARC, I only see this when configuring with gas and gld, which isn't
apparent
in your g++ -v output.

On x86, I see the error with Sun as and gas with Sun ld and gas with GNU ld.
