Compiling with /Zi and no other switches causes certain code motion
optimizations to be suppressed, i.e, the code generated for a program
with the defaults and with /Zi may differ.
   You can override this default behavior by explicitly specifying the
default optimizations on the command line. For example, you can
compile with the following command line to get the same code with or
without /Zi:

   cl /Zi /Ot file.c
