I can try to stick there an assert whether for FUNCTION_DECL
(DECL_INITIAL (decl) == 0) == DECL_EXTERNAL (decl).
Tried that, but cancelled that quickly, I see lots of cases where
DECL_INITIAL is non-NULL, but DECL_EXTERNAL is set, and some
where DECL_INITIAL is NULL, and DECL_EXTERNAL is not set,
at least in the other two spots (check_global_declaration in cgraphunit.c
and c-decl.c). Haven't waited long enough to find out if the C++ FE is some
exception.
My thought was that if DECL_INITIAL is non-null, the function is
defined, so it seems odd to warn about a lack of definition.
