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)
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.
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).
