Re: etags: function not indexed after macro

Dear Roman,

the etags bug that you signaled:

as Eli Zaretskii correctly explains, has an easy and recommended
workaround.

I will try nonetheless to correct the bug, but I am not sure if this can
be done, because of the way the etags parser is implemented.  Do you
have any strong reasons why you should use this style

================
   #define DECLARE_TEST(name) static int test_##name;
   
   DECLARE_TEST(var)
================

rather than this style?

================
   #define DECLARE_TEST(name) static int test_##name
   
   DECLARE_TEST(var);
================

Thank for your bug report, and please try to answer my question.
