The check is to ensure that everyone uses the same version of indent. 
That way ``obvious'' re-indentation doesn't cause unnecessary entropy.
(BTW, re-indentation isn't normally a reason for adding a (C) 2002 to a 
file.  For symtab.h, it had seen other [minor] changes so it doesn't hurt.)

Can you please find out exactly what was changed?  By definition (baring 
a really bad bug) GDB's indentation style is determined by the output 
(no matter how bad :-) of [current] GNU indent with out any parameters 
(ignoring -T).  When a new indent becomes available we should move to it.

I'll tweak the script so that it simply rejects wrong indent versions.

Joel,

W.r.t. indent --<white-space-instead-of-tab>, that is somebody elses 
problem :-)  GDB simply lives with the output of  GNU indent -T ..., no 
matter how bad it is :-)  If EMACS/indent ever change their default, 
we'll change as well.

enjoy,
Andrew
