I think the --tag problem appears when using ccache. Disabling
ccache or arranging for it to be hidden under g++ (symlink) would fix
the issue. It would be better if libtool knew about ccache, of
course.
I tracked down the problem, it comes from the way automake invokes
libtool. I have submitted the 3-line patch below to the automake ML
(adds shell quoting to the compiler name). The --tag stuff is new in the
libtool 1.5.x serie, that's why it never b0rked before.
Debian users can temporarily fix it by installing the libtool1.4 package.
