   According to the manual pages on most UNIX systems, malloc() is defined as:
	char *malloc(size)
	      unsigned size;
so a (char *) pointer to the chunk of memory asked for (if enough memory
exists) is returned, and you cast the pointer to whatever your need is.
    You might have mistaken the unsigned size for an unsigned long.....with
the constant revisions going on, it's not hard to get turned around! :>
