[Bug translator/5955] New: declaration of global variables with semicolon gives semantic error.

["srinivasa at in dot ibm dot com" <sourceware-bugzilla at sourceware dot org>]

Environment: 2.6.24 kernel, systemtap 20080315 snapshot and elfutils-0.130

stap throws up the semantic error messages when global variables are declared
with semicolon.
==========================
[root@llm27lp1 obj]# cat a.stp
        global array;

        probe syscall.open {
                array[pid()]++;
        }
        ...................
        ................


==========================
[root@llm27lp1 obj]# ./stap -vvv a.stp

=====================================

As systemtap allows semicolon at the end of statements(eventhough if it is not
required), it should also allow semicolon at the end of global declaration
statement. A C-programmer(kernel developer to be precise) may commit this
mistake frequently.
