There was a typo at (patched) line 82: "#if define(BOOST_HAS_WINTHREADS)"
instead of "#if defined(BOOST_HAS_WINTHREADS)".

IIRC we earlier discussed checking for a valid TSS index before calling
TlsSetValue when in the cleanup_slots context. Further, I'd suggest
statically initializing tss_data_native_key to 0xFFFFFFFF instead of having
it zero initialized.

The attached patch file (against RC_1_34_0) has these things fixed/added.
Please review. I've applied the patch and successfully run all tests under
libs/thread/test for current RC_1_34_0 under WinXP SP2 (SMP + HT). My own
tests also keep running successfully with the patch applied.

Even though the patch "couldn't possibly" have any effects under non-windows
platforms I also applied the patch and ran the tests under OpenSUSE 10.2
using gcc 4.1.2.

Adding a named constant instead of hardcoding 0xFFFFFFFF all over the place
would also be great. However, as I believe this is the last Boost release
containing the "original" thread code I guess the point is moot?

[A bit off-topic] Is it intentional to have the 1.34.1 updates go under the
RC_1_34_0 branch?

Thanks / Johan
