The problem with the above solution is that now 'print_version' is
a global function that might conflict with another '.c' file that
contained the same construct.  This is not much different from removing
the 'static' declaration from 'rcsid'.  And of course if you declare
'print_version' as 'static' then the function is not used :).  

I realize that 'pragma' means non-standard, but :) is there a 'common'
one used for the above.  On an SVR3 system I've seen '#ident' for what
I want.  On an SVR4 system I saw '#pragma ident'.  If there was a pragma
included in GCC to do such a thing then I could always '#ifdef __GNUC__'
and get the warning everywhere else.  I might be able to live with
that.
