hmm, that don't look too pretty.  Any suggestions on how to extract the errors
in a way that's useful?  Maybe not include the gcc invocation that caused
the(though it could be important I guess)?

Errors have error: prefixes in the diagnostic.  The code has probably something
like:
extern type e_util_unicode_get_utf8 (arguments);
or
type e_util_unicode_get_utf8 (arguments);
in the header, and
static type e_util_unicode_get_utf8 (arguments)
{
  body;
}
definition in the body.  This is invalid C, the prototype must use static
keyword if the definition is static (though, it is questionable why to provide
prototypes for static functions in a header, rather than in the .c file itself,
as other CUs can't access it anyway).

So the header has:

char *e_util_unicode_get_utf8 (const char *text, gunichar * out);

and the c file has:

G_INLINE_FUNC char *
e_util_unicode_get_utf8 (const char *text, gunichar * out)
{
        *out = g_utf8_get_char (text);

        return (G_UNLIKELY (*out == (gunichar) - 1)) ? NULL :
            g_utf8_next_char (text);
}


Doesn't look like to me it matches either of the scenarios above, but my C is
not very good at all.  Jakub can you take a look and clue me in?  (:

Turned out to be a bug in glib2, which has since been fixed.  Rebuild now succeeds.
