For example
https://github.com/erlang/otp/blob/maint/erts/emulator/beam/erl_term.h#L311

        #define is_arity_value(x)       (((x) & _TAG_HEADER_MASK) == _TAG_HEADER_ARITYVAL)

is_arity_value is not recognised as definition but

but the next line:

        #define is_sane_arity_value(x)  ((((x) & _TAG_HEADER_MASK) == _TAG_HEADER_ARITYVAL) && \
                                         (((x) >> _HEADER_ARITY_OFFS) <= MAX_ARITYVAL))

is_sane_arity_value is recognised as definition.

To demonstrate:

$ global -x "is_arity_value"
[no output]
$ global -x "is_sane_arity_value"
is_sane_arity_value  314 erl_term.h       #define is_sane_arity_value(x)        ((((x) & _TAG_HEADER_MASK) == _TAG_HEADER_ARITYVAL) && \

Oddd?
