  # We cannot build the MSVC version with /GL (whole program optimization) because we run into linker error
  # LNK1237, which is a failure to link against a symbol from a library compiled with /GL. The whole program
  # optimization tries to do away with references to this symbol. The solution is to not compile the stack
  # check libs with /GL

  # We cannot build the GCC version with LTO (link time optimization) because we run into linker errors where
  # the stack cookie variable has been optimized away, as it looks to GCC like the variable is not used, because
  # the compiler inserts the usage.
