PR c/71858
* c-common.h (enum lookup_name_fuzzy_kind): Add
FUZZY_LOOKUP_FUNCTION_NAME.
* c-decl.c (implicit_decl_warning): Use FUZZY_LOOKUP_FUNCTION_NAME
instead of FUZZY_LOOKUP_NAME.
(lookup_name_fuzzy): For FUZZY_LOOKUP_FUNCTION_NAME consider
FUNCTION_DECLs, {VAR,PARM}_DECLs function pointers and macros.
* gcc.dg/spellcheck-identifiers-3.c: New test.
