Hi Eric,

thanks. I'll look into this during one of the next days.  The only merge
conflict I saw were, however, just lines preceding the actual change.

Well, my knowledge of ObjC and ObjC++ might be even more limited (my main
interest is the TeXlive build system that uses such files -- if and only if
building for darwin).

Anyway, it may be difficult to cook up ObjC and ObjC++ examples that can be
compiled and linked with all sort of compilers (on darwin as well as
non-darwin systems).  But as a minimal test one might ensure that the
switching to/from ObjC++ works (as now in '260: AC_LANG_OBJC' under 'Testing
autoconf/c macros') and that the appropriate variables get substituted or
some such.

I must, however, admit that I don't understand where the majority of these
tests originate.  This mostly looks quite miraculous to me.
