   Prezados,

    Considerando o seguinte codigo:

$path=$ARGV[0];
open(MW,$path);
read MW,$buff,1024;
close ($buff);
print unpack('h1024',$buff);
print "\n";

   No linux eu rodo e tenho:

  Alguem sabe me explicar porque o *mesmo* codigo, aplicado ao *mesmo* 
executavel da' dumps diferentes? (comparando a 3a linha dos dois, enquanto 
um tem "e2d0d0a042", o do windows tem "e2d0a042", ou seja, o windows 
"comeu" um "d0").

   Versoes do perl:

This is perl, v5.8.0 built for i386-linux-thread-multi
This is perl, v5.8.7 built for MSWin32-x86-multi-thread
