Ensure that this line
#include <time.h>
is in this file
7/src/Machines/standard/etime.c

If it was then try this: edit etime.c and change CLK_TCK to CLOCKS_PER_SEC.

If the problem still remains then go back to the original etime.c;
it might be due to screwy preprocessor issues, but something weird is afoot.
Look in the time.h header file for CLK_TCK.
It is probably /usr/include/time.h and CLK_TCK is probably defined similarly to

# if !defined __STRICT_ANSI__ && !defined __USE_XOPEN2K
# ifndef CLK_TCK
# define CLK_TCK CLOCKS_PER_SEC
# endif
# endif

figure out how to enforce the definition of CLK_TCK; perhaps by stuffing
the define from time.h into etime.c

I suggest that you upgrade to amber 9.
