G++ is a poor compiler to test for optimization and speed. Use VC8 instead. It produces one of the tightest code so far.
Ahem, can you please be a bit more specific ? There are quite substantial differences between different versions. g++ 4.1 is actually very good (though, unfortunately some of boost.mpl doesn't compile with g++ 4.1.1 due to some obscure bug).
All of them. We've been testing fusion with different compilers in different platforms and so far g++ trails behind VC++ in all tests. If you not convinced, please see Boost CVS. In libs/fusion/example/ performance, you can find some tests. Try to beat VC8's results. g++ produces bigger and slower code in general. I chuckle when people show benchmarks with g++ alone and proclaim that library A is better than library B. I am not an MS fan but the fact is that VC++ beats g++ with extreme TMP (inlining, templates, small objects optimization, etc).
