Well, the 4.7 error you get here is due unsupport posix-threading support for
libjava on Windows targets.  Not sure if I want to enhance libjava that it
supports this feature.

A question about this build-failure.  Were you using posix-threading model for
4.6 ?

It's been a while, but I believe the 4.6 was normal win32 threading.

I can't speak for Ruben, but now that thread models have been inextricably
entwined into the core compiler, libjava really should be updated to handle
mingw64's posix thread support. It shouldn't be too difficult, but does require
some unraveling of the various Posix/Win32 native functions.

I think the main problem is the lack of any decent signal handling in win32. As
such, files such as:

libjava/java/lang/natWin32Process.cc
libjava/gnu/java/nio/natVMSelectorWin32.cc

seem to involve event handling that is linked to Win32 threading model,
specifically using the _Jv_Win32GetInterruptEvent() function. It appears that
libjava/win32-threads.cc also has some similarities to the underlying
pthread_cond* implementation in mingw-w64's pthreads library, so in theory it
could just be a matter of porting the interrupt event handlers to
posix-threads.cc to provide ifdef'd alternates to the signal handlers.

Alternatively, Kai and friends at mingw-w64 could implement improved signal
handling in librt, but that may be defeating the purpose of mingw.
