Are you building > with high -j? That's unrelated. There's a race in the krb5 build where multiple components depend on the same generated header file (spnego_something). With high -j, it is possible for these Makefiles to run asn1_compile simultaneously, resulting in an empty header file. Since an empty file is valid, the compiler doesn't react until much later, when a different part of the code references symbols that should have been declared in the now-empty header.
