Re: [cedet-semantic] cedet-semantic Digest, Vol 50, Issue 1

Eric,

FYI, I'm finding this fix isn't sufficient, at least from a display vantage.

When I simply have the following in my .emacs:

(setq semantic-c-takeover-hideif t)
(setq hif-ifx-regexp (concat hif-cpp-prefix
"\\(elif\\|if\\(n?def\\)?\\)[ \t]+"))

I get the error "(void-variable hif-cpp-prefix)".  So, you need to
precede the setq with "(require 'semantic-c)" or "(require 'hideif)"

>From there, my .emacs loads OK, but my code looks like:
#ifdef FOO
...<code here is displayed>
#elif defined BAR
...<code here is displayed>
#else...
#endif

(my hide-ifdef-define-alist has a list that IDs BAR and not FOO)
If I change the "#elif" line to
#elif defined (BAR)

and call hide-ifdefs, the same regions displays as follows:
#ifdef FOO...
#else
...<code here is displayed>
#endif

So the problem seems more involved.

Thanks,

Nate
