Thanks David, that's helpful information. I'll likely give it a go. So does clang create better binaries and libraries, in terms of performance and such-like? I'm currently reading as much as I can find about clang and its associated tools; however, compilers are quite complex software and learning about them is, for me at least, a lot to take in. Best wishes, Jamie.
