I am thinking maybe you turned on or off the runtime library.
Without the RTLDLL, errno is a variable.
With the RTL, it is a function: GetErrno().
If you have old objects compiled without RTL, and are now linking with
RTL, then they wouldn't find an errno.

Recheck your settings, then recompile the entire project. (delete all
objs to force it if you must)

Pathing problems would have more than one minor error.
