* c-decl.c (match_builtin_function_types): New subroutine of
duplicate_decls to test whether a redeclaration of a builtin
function is suitably close, i.e. the return type and all of
the argument types have the same modes as the builtin expects.
(duplicate_decls): Fuzzy type matching for builtin functions
moved to match_builtin_function_types.
