Re: lib/44741: strtod convert 0.010000000000000000057612911342378542997169 incorrectly

[Alexander Nasonov <alnsn%yandex.ru@localhost>]

The bug is incorrect and should be closed.

strtod returns a number bit-to-bit identical to a floating-point
literal 0.010000000000000000057612911342378542997169. I use gcc 4.1.3.

I also checked using math/gsl and bc(1) that a binary representation of
that literal (1.0100011110101110000101000111101011100001010001111011*2^-7)
is closer to original decimal value than two nearest binaries (with 010
and 100 in least significant places).
