OPT_ENDTABLE does not initalise all the elements in stuct opt_table.
When compliling with -Wextra -Wmissing-field-initializers is enabled,
which produces the following warning:
iviewiir.c:299:9: error: missing field 'cb' initializer
[-Wmissing-field-initializers]
OPT_ENDTABLE
^
In file included from iviewiir.c:12:
./ccan/opt/opt.h:82:38: note: instantiated from:
#define OPT_ENDTABLE { NULL, OPT_END }
^
By changing the definition of OPT_ENDTABLE to initalise all 7 elements
of struct opt_table, the warning is silenced.
