Hi

https://github.com/pharo-project/pharo-vm/commit/bc5fda682bbe08bfa33c5c8b6ab2de02621a4131 added support for high res clock on ARM64 linux, however it broke Windows ARM64 build. The issue is due to removed defined(_M_ARM64) in the above mentioned commit, which causes the case switches on ARM64 Windows to fallback to

#elif defined(_WIN32)
   value = __rdtsc();
#else

__rdtsc is not available on ARM64 architectures: https://learn.microsoft.com/en-us/cpp/intrinsics/rdtsc?view=msvc-170
