gcc 64bit compilation:urgent

[Rajdeep Sengupta]

Hi Team,

I want to compile gcc version3.0.4 in 64bit mode , Though I am not sure
if at all it is possible or not.
So can U please tell me whether it is possible or not and also the steps
for doing that.

I have a 64bit 280R machine loaded with solaris 2.8 .

Thanks
