Revised patch for libio test breakage

[Zack Weinberg]

Under glibc 2.1 in default mode a declaration of malloc is visible
after including string.h.   It clashes with the private, old-style
declaration of malloc in dbz.c and dbzmain.c.  This causes a naive
'make check' to bomb out before it ever reaches the interesting bits.

Since we attempt to provide a sensible stdlib.h even on unregenerate
K+R systems, and dbz.c/dbzmain.c are only compiled by GCC, this patch
simply nukes the private decls and includes stdlib.h unconditionally.

OK to install?

zw

	* dbz/dbz.c: Nuke private decls of malloc, calloc, free, atoi,
	atol, and errno.  Include stdlib.h.
	* dbz/dbzmain.c: Likewise.
