There is another problem with arc for unix I discovered while
running it on a UNIXPC.  The file arcunix.c contains a function
called xrealloc().  This procedure calls realloc.  Unfortunately,
since realloc was #defined to be xrealloc in arc.h, this causes
a recursive call indefinitely, resulting in process death from
lack of swap space (on the Unix PC anyway).  This occurs, for
example, whenever trying to add more than one file at a time
to the archive.

The fix is simple: #undef realloc 
put this right before the realloc call in xrealloc.  You may
also want to do something like: extern char * realloc
to avoid a warning message during compiling.
