--- Comment #5 from David Edelsohn <dje at gcc dot gnu.org> ---
Previously the test case was unresolved because it referenced alloca without a
declaration.
char *adata = (char *) alloca (n);
If you want to call __builtin_alloca() because this is a testcase for GCC,
which provides __builtin_alloca(), fine. You should call it directly and not
alloca().
If you want to call alloca(), then you need logic for the different systems
that declare alloca() in different header files.
#ifdef alloca
is wrong because it makes the testcase system dependent and tests different
behavior.
