Adam,

   I've never been in your situation, but it appears evident that you're
missing the header which defines error values. I suspect you'll find
that scripts/kconfig/mconf.c should include /usr/include/linux/errno.h,
or a header which in turn includes it, so you'll have:

#define  EINTR     4 /* Interrupted system call */

The same goes for EAGAIN. It's defined in the same file, naturally.

Can you post the #includes at the top of scripts/kconfig/mconf.c?
If the include is there, then your include path probably needs tweaking.
