keep dreaming, more poeple use GCC then MSVC because it's free, portable and doesn't require the slow and bloated .NET to install. Your facts are twisted.
GCC is slower because it does more work it producing binaries that are smaller and more efficient then the horrible bloated messes produced by MSVC and CLANG. It makes more more sense: Compile once and run many times. Something the BSD homos don't get.
GCC outputs a lot more details that Clang and MSVC try to hide making it easiler to figure out the problem much more quickly.
