obstack_next_free is supposed to return a void*, rather than a char*
as it does currently. Avoid warning on void* arithmetic when
obstack_next_free gets it proper return type. Committing as obvious.
* cp-valprint.c (cp_print_value_fields): Cast obstack_next_free
to char* before doing pointer arithmetic.
