 The applicable code:

 {{{
 #ifndef BOOST_HAS_THREADEX
 // Windows CE doesn't define _beginthreadex
 typedef void* uintptr_t;
 // ... more code
 #endif
 }}}

 For some reason mingw-w64 will evaluate this code. This redefines
 uintptr_t (as well as _beginthreadex related code), which causes the build
 to fail.

 [https://groups.google.com/d/msg/microsoft.public.windowsce.app.development

 /o_7hgu0G-II/VhuEmWk1ROIJ This post] has a solution which avoids defining
 uintptr_t at all, and is targeted specifically for Windows CE rather than
 some arbitrary BOOST_HAS_THREADEX macro define.

 I've created a patch which incorporates the fix and it does compile with
 mingw-w64 (mingw-builds, gcc 4.8.1 targeting windows x64), and doesn't
 break building with VS2012 (really shouldn't break any VS builds targeting
 Win32).

 I don't know when the problem first occurs, but I do know that it fails in
 1.53.0 all the way to trunk (my current working directory is r85020).
