[Gnuk-users] RSA computation

[NIIBE Yutaka]

I tried GCC 4.9 and compiled bignum.o with -O3 (and no -Os).  Then,
RSA sign takes something around 1.3 second.  Very good.

It is known that compiling with -O3 (and no -Os) causes failure of
Chopstx.  I also tried rsa.o with -O3 (and no -Os), and it caused a
failure of key generation.

So, I only enable -O3 option for bignum.o.  Other objects are compiled
with -O3 -Os.
