>Description:
When running MAKE CHECK, floating point tests fail with the following
output:

testing float (without inline functions)
Fail: fdim (9, 0) = 9
Result:
 is:         -9.00000000000000000000e+00  -0x1.20000000000000000000p+3
 should be:   9.00000000000000000000e+00   0x1.20000000000000000000p+3
 difference:  1.80000000000000000000e+01   0x1.20000000000000000000p+4
Fail: fdim (0, -9) = 9
Result:
 is:         -9.00000000000000000000e+00  -0x1.20000000000000000000p+3
 should be:   9.00000000000000000000e+00   0x1.20000000000000000000p+3
 difference:  1.80000000000000000000e+01   0x1.20000000000000000000p+4
Fail: fdim (+inf, 9) = +inf
 Value: -inf  -inf
Fail: fdim (+inf, -9) = +inf
 Value: -inf  -inf
Fail: fdim (+9, -inf) = +inf
 Value: -inf  -inf
Fail: fdim (-9, -inf) = +inf
 Value: -inf  -inf

Test suite completed:
  2158 test cases plus 2146 tests for exception flags executed.
  6 errors occured.

This occurs for each float type 'fdim' function.  All other library tests
pass without any problems.

>How-To-Repeat:
	Run MAKE CHECK...
>Fix:
	Sorry, can't help here, assembler is not my forte.
