Wow! Curious that, after being broken for 2.5 years (at least, that's
when the #include <config.h> was last changed in libiberty/alloca.c),
this should be noticed and fixed just when it's no longer needed.
alloca.o is gone from mainline. Here's what I'm checking in the
3.0 branch to fix the problem:
Index: gcc/ChangeLog
from Brad Lucier <lucier@math.purdue.edu>, Alexandre Oliva <aoliva@redhat.com>
* Makefile.in (alloca.o): Depend on $(GCONFIG_H).
($(HOST_PREFIX_1)alloca.o): Depend on $(HCONFIG_H). Arrange for
hconfig.h to be included.
