+# We need to find alloca() somewhere.  Gcc has one built in, but most other
+# compilers don't.  Using the one in /usr/ucblib/libucb.a is tricky because
+# we have to be careful not to pull in anything else from the library (lots
+# of things are broken in most SVR4 versions).  The best solution is to just
+# compile alloca.c and link it into the executable.  If we end up not needing
+# it, then the code is just dead.  Once alloca.c moves to libiberty, then we
+# can eliminate this semi-kludge.
