current configure.in, 1.213, 1.214 miscutil.c, 1.83, 1.84

Update of /cvsroot/ijbswa/current
In directory sfp-cvs-1.v30.ch3.sourceforge.com:/tmp/cvs-serv28376

Modified Files:
	configure.in miscutil.c 
Log Message:
Let zalloc() use calloc() if it's available

In some situations using calloc() can be faster than
malloc() + memset() and it should never be slower.

In the real world the impact of this change is not
expected to be noticeable.
