[svn-r1595] 
not sure if this is what was wanted but in the code where the file drivers are registered
the end_registration: label was giving me some trouble with compilation on NT.
I think the end_registration label was supposed to be empty and but on NT it didn't
like that so i had to put a semi colon after the label.
if this is wrong let me know and i'll fix it someother way
