Installing GNU tar version 1.11 on a Next running OS release 2.1 revealed the
following:


1.  Files buffer.c and diffarch.c declare valloc() as

	extern char *valloc();

which conflicts with the Next's definition in /usr/include/stdlib.h:

	extern void *valloc(size_t size);


2.  The configure script fails to add -DBSD42 to the list of compilation
definitions.  It checks for the presence of /vmunix, but the Next boots from
/sdmach.

3.  When the final executable is linked, malloc.o is linked in, which causes
name conflicts with malloc, free, ...  in the Next shared libraries.  The
configure shell script test for /vmunix to see whether to use tar's malloc.
