[pph] Add new C test case

[Diego Novillo, 2011-06-01 15:41:12]

This test case from the C testsuite started working after the last
merge from trunk.

Collin, this is the test I was referring to yesterday.  I'm going to
add some more C test cases to the testsuite that are currently not
working.  I think that's going to make our fixing job easier
(otherwise, it's not trivial to test these test cases outside my own
local tree).

Tested on x86_64.  Committed to pph.

Diego.
