commit 828bf6828b048b1482e95f84ca92e5fe0edcdc0c
Author: Joseph Myers <joseph@codesourcery.com>

    Fix i386 exp10 missing underflows (bug 18966).
    
    On i386, the double version of exp10 can miss underflow exceptions if
    the result is in the subnormal range for double but the last 11 bits
    of the 64-bit extended-precision mantissa happen to be zero.  This
    patch forces the exception in a similar way to previous fixes.
    
    As with the exp2 and exp fixes, the exp10f changes may in fact not be
    needed to ensure underflow exceptions, but are included for
    consistency and to fix the exp10 part of bug 18875 by ensuring that
    excess range and precision is removed from underflowing return values.
    
    Tested for x86_64 and x86.
