[Bug c/21800] New: Bogus "control may reach end of non-void function ... being inlined" warning

["mj at ucw dot cz" <gcc-bugzilla at gcc dot gnu dot org>]

`gcc-4.0 -Wall -O2' on the attached piece of code produces the following warning:

s.c: In function 'main':
s.c:15: warning: control may reach end of non-void function 'xtoi' being inlined

which doesn't make much sense as assert_failed() is known not to return. If I
remove the `if (1)', the warning disappears.

The warning doesn't appear in gcc 3.4.4.
