gcc apparently has a hack to make the following broken program compile:

	#include <stdlib.h>
	char *malloc(), *realloc();

but only when <stdlib.h> is found in /usr/include.  mk_cmds/ct.y has
broken code like this, so it compiles if ${DESTDIR} is "/" (otherwise
stdlib.h is found in a nonstandard place).

gcc apparently has a similar hack for `long long'.  If <sys/types.h>
is found in /usr/include/sys, then `gcc -pedantic' doesn't warn about
long longs; otherwise it does.
