[Gm2] gm2-2010-03-25 with pow

[john o goyo]

I created pow.c (infra), compiled it with "gcc -c" (built to produce  
64-bit code by default),
put the object file in gcc/libgcc.a, and then ram "gmake check- 
gm2" (as a low-level experiment).

Here is the output:

# of expected passes            8796
# of unexpected failures        72

Previous results were:

# of expected passes            8730
# of unexpected failures        96
# of unresolved testcases       42

pow.c:

#include <math.h>

double exp10(double x)
{
  return exp(x*M_LN10);
} /* exp10 */

float exp10f(float x)
{
  return expf(x*M_LN10);
} /* exp10f */

long double exp10l(long double x)
{
  return expl(x*M_LN10);
} /* exp10f */
