I'm also surprised with this statement (as a msvc-first user but still use
clang and gcc regularly, but on linux).
Maybe Niall meant mingw instead of gcc.
I don't know how to compare msvc with clang on windows, last time I checked
clang was not ready for production so it wouldn't be a fair comparison.
There also seems to be very different performance characteristics depending
on the kind of code
(metaprog, etc.) from the different compilers so maybe Niall is in a very
specific context.
