Hi Nick,

Thanks for helping with this change.

I'm not sure about the option.  Alpha has somewhat similar code without 
an option.

As I understand it, this code is to handle a number of instructions 
which require a preceding
label.  It usually emitted on the previous line.  It seems to me that 
changing segments between
the label and its related instruction should be an error.  I don't think 
this feature is needed
even for the HP-UX SOM target.

I will check whether GCC needs this for SOM.

Dave
