See Bug 6745 - .ll output is different on windows.
http://llvm.org/bugs/show_bug.cgi?id=6745
On mingw32, PRINTF_EXPONENT_DIGITS affects printf and tests would run
with PRINTF_EXPONENT_DIGITS=2.

An addition, it seems mingw-w64's printf tends to drop minus sign of
"-0.0".
(is it same on i686? is it fixed in trunk?)
