Re: With a wacky macro before it, 'global' appears to miss a function

This feels like the right solution.

ANSI C has been around for a long time... I'm pretty sure we'd be able to turn 
on the ANSI mode, and get the benefit of the better parsing.

Fwiw..  I wonder if old k and r compilers could even handle these wacky macros. 
(if not.. You might never see these in this files..)

   Long term, global might need a way to specify ANSI on a file by file basis 
for really big code bases.  (since some code bases may contain both..)

(or would the preferred solution be to build multiple tag files (some in k and 
r, some in ANSI), and the combine them together somehow?)

Cheers,
--Phil
