Log Message:
lint: in C99 mode, only warn about implicit function declarations

Since tree.c 1.294 from 2021-06-28 (two days ago), lint errored out on
an implicit function declaration.  In principle it is correct to do so
since C99 requires it, but in practice there are a several functions
that are not declared in the translation unit itself since they are
provided by the compiler.  Typical examples for GCC and Clang are the
various functions named '__builtin_*' and '__atomic_*'.

For now, only warn about these but don't error out.
