Can't compile old commits

[Tomohiro Kusumi]

I'm using the current master, and trying to compile some userspace
code (run make under some dir) in a dragonfly commit of about a month
ago, but fails with bunch of these.

This at least occurs with sbin/hammer,hammer2,newfs_hammer,newfs_hammer2.
What are these __malloclike errors ?
