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.
	* cp-valprint.c (cp_print_value_fields): Cast obstack_next_free
	to char* before doing pointer arithmetic.
        * charset.c (convert_between_encodings): Shrink obstack using
        obstack_blank_fast.
        * minsyms.c (install_minimal_symbols): Likewise.
+       * cp-valprint.c (cp_print_value_fields): Cast obstack_next_free
+       to char* before doing pointer arithmetic.
