Yes. This is because the way Semantic provides symbols to hide-ifdef
does not take into account *where* the symbol is defined; it will just
see it as defined in the current buffer.

This isn't too hard to fix, but I'm in the process of rewriting the
preprocessor handling anyway, and this will be fixed along the way. So
at the moment, it is best to not use this feature, or at least to turn
it off in header files.

Hmm. Parsing should still work. You can use

M-x semantic-dump-parser-warnings

to see what is skipped during parsing.
