The command-line only allows to set this for all warnings/hints/notes.

  -Se<x>     Error options. <x> is a combination of the following:
          <n> : Compiler halts after the <n> errors (default is 1)
          h : Compiler also halts after hints
          n : Compiler also halts after notes
          w : Compiler also halts after warnings

I didn't see a way to do this for specific message numbers.
I think at this point your best bet is to create a small include file that is included in all files ?
