Problem timing execution

[Timothy Rost]

I am trying to time the execution of my program to compare the
efficiency of different compilers.  However,  I keep getting error while
trying to compile.

Here is a small bit from my code ...

#include <time.h>
clock_t clk;
clk = clock();

Whenever I add the clk = clock() line I get the following errors during
compilation; otherwise it compiles fine.

/usr/local/m68k-coff/lib/libc.a(timer.o): In function '_times_r':
/usr/local/src/m68k/build/m68k-coff/newlib/libc/reent/
../../../../../src/newlib/libc/reent/timer.c:63: undefined reference to
'times'
/usr/local/m68k-coff/lib/libc.a(timer.o): In function '_gettimeofday_r':
/usr/local/src/m68k/build/m68k-coff/newlib/libc/reent
../../../../../src/newlib/libc/reent/timer.c:107: undefined reference to
'gettimeofday'

I'm using gcc-2.8.1, binutils-2.9.1, newlib-1.8.1, and libstdc++-2.8.1.1
running of RedHat Linux 5.1

Any ideas would be greatly appreciated.
