I needed to update headers to be able to recompile ifconfig after some
additions; then got bitten by that not compiling as libc didn't include
the symbol for _ThreadRuneLocale yet but the header was already picked up.
So had to re-do libc as well.

Doing a make clean cleandepend obj depend all install for expr and yacc
has helped and re-starting buildworld succeeded.

So /usr/include/osrealdate.h being updated was the culprit most likely.
*grml* fragile stuff.  I can see the point though.

   It does not matter how good you are. It matters what good you do!
