Fix an error at I386:
zmwatch[2429].ERR [Shared data size conflict in shared_data for monitor Monitor-1, expected 328, got 316]

The patch for i386 ($arch should be 32 here but perl uses 64 bit integer):

-our $arch = int(3.2*length(~0));

+our $arch = 32;

I'm not sure how to properly fix this. I'm all ears.
