I'm not sure why you think SSE2 can fix this issue.
The ruby_strtod function used in converting string value to double
value requires double-precision (53-bit) rounding precision but
mingw32 gcc 4.5.2 have default 64-bit precision which higher than
other compilers.
So the patch lowers precision from 64 bit to 53 bit.
