Hi Mr  Natarajan,
responding is not a problem.  but giving the correct reply regards legal
issues I cannot do.

this mail I have not seen, normally I pay high attention to any news
from AMD  since I use your
CPU on a daily base.  I read and discuss on this list which is also
accessible from

NNTP and webmail,

On  snews.gmane.org   NNTP I cannot see it.


http://gmplib.org/list-archives/gmp-discuss/2008-April/thread.html

the mail from 14.th April is to me not existent.

So I read this list from three sources, and I think it could be that it
was by accident
declared as *****SP4M*****    I only subscribe at gmp-discuss. 

however this mail is present in my inbox,  in my NNTP account and from
the gmane account.

I am certain someone with more competence will reply you.

You did not mention which C++ compiler you are using, 
gcc please?  which version ?

Microsoft visual studio ? 

which operating system?   BSD  Gnu/ Linux or Windows?

best regards

Morten
