Mark Allen 552216f9ba scripted symbol name change (ompi_ prefix) 
Passed the below set of symbols into a script that added ompi_ to them all.

Note that if processing a symbol named "foo" the script turns
    foo  into  ompi_foo
but doesn't turn
    foobar  into  ompi_foobar

But beyond that the script is blind to C syntax, so it hits strings and
comments etc as well as vars/functions.
