8817	Boost Thread Windows CE _createthreadex handling breaks mingw w64	Andrew Ho <helloworld922@…>	viboes	"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)."	Bugs	closed	Boost 1.55.0	thread	Boost 1.54.0	Problem	fixed	MinGW uintptr_t	jim@…
