The commit logs aren't quite the right place for describing the (apparently) not very well known intricacies in libm, but neither is the code, especially here since I plan to optimize the float case by not using floats internally and then the intricacies in e_rem_pio2f.c will mostly go away. This one will move to e_rem_pio2.c if we start porperly supporting long double precision on i386's before gcc properly supports double precision on i386's, but I want to keep e_rem_pio2.c in sync with the vendor version.
