Re: [CEDET-devel] completion problem with conditionals in includes

[Eric M. L. <er...@si...>]

Ah, I was worried about that.  This is something I don't think any
tagging utilities will work with since all the code involved in the
smart completion and such assumes a static named space unrelated to
position in the code you are completing in.

Your best bet is probably to pick what is most likely the value, and
set it explicitly in the c-mode-hook based on filename perhaps.
