+	* include/kaffe/jmalloc.h:
+	Avoid KFREE() related "type punning" warnings in gcc 3.x
+	when compiling using --with-vmdebug.
+
+	This revert's egp's changes which were to "Avoid casting in
+	call to KFREE().".  I didn't understand why that was an
+	issue (or even why we're zeroing out the pointers, in the
+	first place, I assume it's got something to do with some
+	gc interaction).

 	* configure.in:
 	Check for stdarg.h (needed by valist.m4 varargs
 	checks, otherwise varargs.h is used, which fails
