RFR: 8212826: Make PtrQueue free list lock-free - Build error in gtest

[Langer, Christoph]

Hi Kim,

my configure says:
* Toolchain:      microsoft (Microsoft Visual Studio 2017)
* C Compiler:     Version 19.16.27024.1 (at /cygdrive/c/progra~2/mib055~1/2017/profes~1/vc/tools/msvc/1416~1.270/bin/hostx86/x64/cl)
* C++ Compiler:   Version 19.16.27024.1 (at /cygdrive/c/progra~2/mib055~1/2017/profes~1/vc/tools/msvc/1416~1.270/bin/hostx86/x64/cl)

So it probably has to do with that newer version...

Best regards
Christoph
