5d8d8dd3b6 Use the C library version of log10() instead of the inaccurate formula
log10(x) = log10e * log(x).  This fixes some small (one or two ULP)
inaccuracies.

9e2d0733c5 Oops, I thought I was fixing the double precision lg10 in the
previous revision.  Use log10f() instead of log10().  log10f() is
currently slightly slower than log10() on P5's, but it is potentially
significantly faster.

Fixed declaration of the C function used in the (unused?) KR_headers
case.

799e5901b3 Use the C library version of log10() instead of the inaccurate formula
log10(x) = log10e * log(x).  The formula would work if the RHS were
evaluated in extended precision with an extended precision log().
This actually happened with the i387 log() because it returns excess
precision.
