It seems you're a little bit outdated with your release. ;-)

Xenix 386 2.3.2 comes with: 
      Microsoft 386 Compiler ver. 4.85
                ( was updated with lng095 to ver 5.1)
      Microsoft 286 Compiler Ver. 5.1 
      Unix 5.3 C Preprocessor
      Unix 5.3 curses

Always 'works ok' with MSC 386 5.1 on my system.

BTW: -Ox is default. And is the same as -Oactl. All three cc-commands
     produce the same code.
