The issue seems to have been fixed in the mean time.

Core: Remove leftover Windows 32-bit functions in MemArena.cpp
DSP: Use completion event for ARAM interrupt
Windows: Give SCMRevGen a configuration for x64 instead of Win32.
Placed ampersands and asterisks against type name
DSP: General cleanup. No behaviour change.
Removed warnings by explicitly casting to `u8` for controllers
FrameTools.cpp: Alignment of long lists
Windows: Use a shared precompiled header for dolphin code under Source/
Externals: update Bochs to newer version

Should resolve the disassembler not handling all the opcodes Dolphin generates.
Windows: Add /Zc:inline to compiler options.
Merge pull request #806 from archshift/readability

FrameTools.cpp: Alignment of long lists
Merge pull request #795 from ChuckRozhon/correct_pointer_style_tasinputdlg

Placed ampersands and asterisks against type name
Merge pull request #808 from FioraAeterna/bochs

Externals: update Bochs to newer version
Debugger: fix blowup calculation again

Wasn't quiiite right in 3c2567 either.
OGL: Fix brace and body placements

Also got rid of void argument specifiers. These are a carryover from C.
OGL: Clean up parameters for some functions.
OGL: Add static to a function in NativeVertexFormat
Removed warning caused by calling std::min<int> with size_t values
JIT: don't rely on undefined behavior for constant overflow checking

I have no idea what the compiler does with these, and this code probably
isn't triggered in most games, but it's probably better not to taunt the
undefined behavior demon.
