[Fujii Hironori]

This is a MSVC bug fixed in the latest.
https://developercommunity.visualstudio.com/content/problem/315575/overload-resolution-for-built-in-operator-and-enum.html

WebKit can't update MSVC due to other bug (Bug 188635).

This issue happens under following conditions:

* LayoutUnit has non-explicit constructors
* using namespace WebCore
* X86Assembler.h is included after using namespace WebCore


There are possible workarounds:

* Include programmatic JSC header files before using namespace
* Remove all "using namespace {WebCore|WebKit};" in Source/WebKit/WebProcess/InjectedBundle/API/c/*.cpp
* Remove non-explicit constructors of LayoutUnit
* Do not unify source files in Source/WebKit/WebProcess/InjectedBundle/API/c/*.cpp
* Update MSVC (Bug 188635)

[Fujii Hironori]

Remaining Task:

r235845 <https://trac.webkit.org/changeset/235845> should be reverted after the MSVC issue will be fixed and WinCairo build bots will be switched to the new VS (Bug 189987).

I think we should probably remove the "using namespace" statements in question.

[Fujii Hironori]

This issue happens several times. And, it seems that it will take more time for Microsoft to fix the bug.
We need a effective workaround not to repeat this issue until they fix MSVC.
I think I should remove ": int8_t" of RegisterID only for COMPILER(MSVC).

You should do this in a separate bug.  Our practice is 1 change per bug.

Agreed.
Thank you for the feedback. I will do so.
