e.g.

  product(bool, ForceTimeHighResolution, false, \
          "Using high time resolution (for Win32 only)") \

  product(bool, MaxFDLimit, true, \
          "Bump the number of file descriptors to maximum (Unix only)") \

  product(bool, PerfBypassFileSystemCheck, false, \
          "Bypass Win32 file system criteria checks (Windows Only)") \
                                                                            \
  product(intx, UnguardOnExecutionViolation, 0, \
          "Unguard page and retry on no-execute fault (Win32 only) " \
          "0=off, 1=conservative, 2=aggressive") \
          range(0, 2) \

They should be moved to globals_windows.hpp or others?
