[Bug c/32207] missing warnings about address of 'x'.

[pluto at agmk dot net]

------- Comment #2 from pluto at agmk dot net  2008-02-05 19:32 -------
for f()/g() it partially looks like missed transformation of `z!=0 => z`
in case of ADDR_EXPR which trigs different diagnotic:

f(): c-common.c: c_common_truthvalue_conversion with ADDR_EXPR.
g(): c-typeck.c: build_binary_op: case NE_EXPR, with op ADDR_EXPR.

for h() the -tree-original shows an ugly cast in `if`: (void*)z!=0
is it an expected behaviour?
