Just Launched: You can now import projects and releases from Google Code onto SourceForge
We are excited to release new functionality to enable a 1-click import from Google Code onto the Allura platform on SourceForge. You can import tickets, wikis, source, releases, and more with a few simple steps. Read More

My previous mail reader deleted a pile of my old mail, so I'm bodging
this reply together.
The __THROW should be accounted for in the preprocessor map by default.
There are 5 symbols that show up by default which are:
("__THROW" . "")
("__const" . "const")
("__restrict" . "")
("__declspec" . ((spp-arg-list ("foo") 1 . 2)))
("__attribute__" . ((spp-arg-list ("foo") 1 . 2)))
As such, you shouldn't need your one set command below.
When I stuck the sample you provided in a buffer, it parsed fine. I
found that fcn in one of my local headers, and it was parsed fine there
I'd guess there might be something else in the header, such as a #ifdef
or other that might be getting in the way.
Sometimes the only way to figure it out is to take the header, parse it,
then start deleting large chunks of the buffer away till it does start
working, then you can narrow down what the problem is. Once you know
what it is, then it will probably be easy to come up with a workaround.
