There's more uses of BOOST_HAS_THREADS, but looking at them (including those in the regex headers), it seems to me that BOOST_HAS_THREADS really ought to be defined for a multi-threaded build, even if /Za is specified, otherwise the code won't be thread-safe.
Code that depends on <windows.h> will break if /Za is specified, but that's a separate issue to BOOST_DISABLE_THREADS. I'm not suggesting we should be able to *build* boost with /Za, just use it.
I would prefer not to make this change to Boost.Config for 1.35, but we should try to find a decent way of handling this.
I was thinking that we didn't fix this in 1.34, so we ought to try and fix it in 1.35.
Well, how about you run the full regressions tests with /Za both with and without the config changes and see what happens? Regards, John.
