Retry: Question about FutureWarning

I'm trying again, since no response indicates that I'm not providing 
enough info.

I have module M1 which has the following line in it:

    StartTime   = safe_dict_get ( dic, 'starttime', 0xFFFFFFFF )

It gets imported by modules M2 and M3. And finally, M4 imports both M2 and
M3. So the idea is that in total we have 4 files called 

   | |\M1
   | |\M1

I need to compile the python modules as part of the package building 

The shell compile command I use to generate both the .pyc and the .pyo 
files is:

i_python ()
      $python -c "import $1"
      $python -O -c "import $1"
i_python M1
i_python M2
i_python M3
i_python M4

When M1 is compiled, there's no problem. The same for when I compile M2
and M3. But when M4 is compiled, I get the following message: FutureWarning: hex/oct constants > sys.maxint will
return positive values in Python 2.4 and up
    StartTime   = safe_dict_get ( dic, 'starttime', 0xFFFFFFFF )

I get the message twice, ostensibly because of M3 and M2 both being 
imported into M1

I was able to shut off the warning by adding the following lines *before*
the import of M2 and M3 in M4:

import warnings
warnings.filterwarnings('ignore', category=FutureWarning)

My question is this: Why can the warning not be shut off by putting the
two lines in M1 where the reference exists to 0xFFFFFFFF ?

I'm just leary of fixing warnings by looking for ways to shut them off.

Also, do I need to supply any more information?

Thanks for your patience.
