Originally I sent the attached message to the GNU Emacs help mailing
list, but perhaps people on this list could have useful advice for me as
well.  Thanks in advance.

Hello users of the greatest editor of all times!

I'm working on a libguile-based project.  All function definitions that
are exported from C code to the Guile interpreter are define like this:
(meta-variables between '<' and '>')

SCM_DEFINE (<c-name>, <scheme-name>,
            <mandatory-args-count>, <optional-args-count>, <rest-bool>,
            <argument-list>,
	    <documentation-string>)
{
 <function-body>
}

At C preprocessing time the 'SCM_DEFINE (...)' function header gets
expanded to:

SCM
<c-name> <c-argument-list>

Unfortunately Semantic doesn't recognize it as a function definition.
How can I make Semantic recognize it as such?

I don’t know about Semantic, but I know that GNU GLOBAL doesn’t have any
problems dealing with SCM_DEFINE’d functions.

So perhaps the simplest way is to use xgtags.el or similar, or to tell
Semantic to use GLOBAL as its back-end (info "(semantic) SymRef")?

Thank you for pointing out that GNU GLOBAL deal with SCM_DEFINE'd
functions just fine.  I ended up using ggtags as it seems Semantic
doesn't use GNU GLOBAL database for 'semantic-complete-jump' and
'semantic-ia-fast-jump', despite its use of it in searches of symbol
references.  I'm still using Semantic for other things, in particular
for mode-line documentation, as ggtags' Eldoc support is not working for
me, and Semantic is able to grab the prototype of SCM_DEFINE'd functions
from the header files.
