final message interpreted as a match about ggtags HOT 2 OPEN

Hi @p-m,

Upstream may have changed something.

See the definition of (define-compilation-mode ggtags-global-mode... which overrides a bunch of compilation-mode variables. In particular, check compilation-error-regexp-alist is correctly set and in ggtags-global-error-regexp-alist-alist.

What I find really useful in dealing with similar situation is get a copy of compile.el from 27 and master and diff them to find suspicious changes.

Thanks. Indeed, after removing line 1685, it works.
(The count is still wrong, but it's not really important.)

Please find attached the diff.
