New pthreads-w32 releases available: versions 2.3.0 and 1.7.0

[Alexander Terekhov]

[... named mutex and atrocities of MS impl ...]

It's not that hard to implement it using a map with pointers (to
"normal" mutex + refcount structure and addresses of once_control
variables as keys).

[... Windows Interlocked stuff ...]

In the meantime, MS has documented that they are fully fenced
(newer Acq/Rel stuff aside for a moment).

But you'll need acquire semantics for check on fast path. Not a
problem on IA32 (where all loads do have acquire semantics), but
on IA64 (lets pretend that it's still alive ;-) ), you'll need a
bit of assembly to make it fast.
