Hello.
Taking the notes from Joseph under consideration, I have developed a
fairly working patch for roundeven, attached herewith.
I have done bit-wise calculations to check for halfway cases, though
HOST_WIDE_INT is only used to check for even and odd numbers (or is it
necessary to do bit-wise for this too?). Also, why unsigned long
sig[SIGSZ] in real_value has to be an array? (for 64 bit system, its
an array of size 3, mostly first 2 values being 0?).
Thanks.

Regards,
-Tejas
