New Revision: 282994
URL: https://svnweb.freebsd.org/changeset/base/282994
Log:
Provide reallocarray() in -legacy, if needed, to allow building head on
previous releases.
Also add a stdlib.h wrapper, which declares the function, otherwise the
compiler may assume it returns int, which can cause segfaults on LP64
architectures.
