Thanks, but this doesn't solve my problem. What I think you're saying is 
that I should pass target-os=cygwin. But I can't do that in my use case, 
which is going into a library's test directory and typing

b2 
toolset=clang,clang-cxx11,gcc,gcc-cxx11,msvc-8.0,msvc-10.0,msvc-11.0,msvc-12.0

When a test depends on Boost.Thread, it tries to build it, and that fails on 
Cygwin.

I could split the above into two lines, but it would've been nice for Cygwin 
to work out of the box with Boost.Thread. This is why I've been trying to 
come up with a way to change Boost.Thread's Jamfile to use 
<threadapi>pthread on Cygwin and the default <threadapi> on MinGW.
