Having finally worked out the tcl bits, and a couple of non-regressions
that showed up during a merge, I've committed the following.
This is great stuff and I may have a use for it... but was it really
necessary to commit during Stage 3, when we seem to be having a
remarkable amount of trouble getting the next release together?
I can't see any conceivable interpretation of this as a regression.
About this, I would be curious to know whether this enhancement benefits
libstdc++/24025, which, if I remember correctly, only affects systems
not defining _GLIBCXX_HAVE_TLS...
