Gah.  AM_PROG_CC_C_O is C only, not C++.
I guess you should be able to use this manually-written rule as a
workaround:

.cpp.$(OBJEXT):
        $(CXXCOMPILE) -c $<

or this (uses undocumented Automake knowledge, thus not advised):
tagdemo_OBJECTS = tagdemo.lo

Reminder to self (or whoever else):  Automake needs to learn that C++
and Fortran 77/90 compilers may not understand `-c -o'.

Cheers,
