Thought I'd let you know, I found another error in the config.log
which was previously a warning:

I don't think this affects the Windows build though; if I compile with
'-Wno-error=int-conversion' the configure script still reports:

checking whether pthread_setname_np takes a single argument... no

It might possibly affect the build on other systems though.
