dholland 933ac46844 signal.h is not supposed to define errno, so use ___errno instead.
Adjust errno.h in a compatible fashion to avoid -Wredundant-decls issues.
I have run a build to check the tree for places where errno.h is missing,
and fixed the cases I found, but there might be more in MD code.
