Which compilers and options do you use to compile x64 engine

[Anonymous]

Sergei Markoff, Smarthink wants to compile his engine for more speed. He wrote me:
It's very important. SmarThink is bitboard engine and outcome from 64-bit version can be ~60%. But I need some advices to do it. I don't know which compiler I must use to do it. I have Intel C/C++ 8, but I have a problems with compiling SmarThink with it ( "Internal compiler error". Current SmarThink version is compiled with Intel C/C++ 7 w/o profile-guided optimization...

I think most people are using MSVC2005 to do 64 bit compiles. Speed is really good, and unlike Intel C, it doesn't continously crash or miscompile code...
