Sorry, I wrote my last post in a hurry – I suppose it's clear 
anyway, but that should have been »by the linker and dyld 
versions Apple shipped with OS X prior to 10.7«.

I don't know the current relative market share of the different 
OS X versions on top of my head either, but as we were getting a 
couple of bug reports from people who had tried to use LDC 2 on 
10.6 (before we figured out that LLVM doesn't emulate TLS there), 
I guess it's too soon to drop support for it still. However, when 
finally somebody finds the time to implement shared library 
support in the runtime, the situation might have already changed 
anyway.
