VS 2008 is somewhat crusty and I don't think is supported for ARM, but that's still a really weird error.  At this point I can't download 1.6.10 to check, but 1.6.9 most definitely should never produce that error for a C90 compliant compiler because <errno.h> is #included and that defines errno!

Apparently <errno.h> was *not* included, because the missing strerror warning is symptomatic of that too, so something is seriously wrong but I'm not sure what.
