I reproduced this with just gcc-core, I normally also build g++ and
gfortran as well. The problem goes away if I unpack the sources for
objc, which I am not really interested in.
Any takers? How/against what do I report this?
The problem is that now configure is processing config-lang.in files
even for languages that are not active by default.
It is a bit weird that objcp is included in the gcc-core download. It
could be included in the gcc-objc download (or in a separate objcp
download). But we can work around the problem by restricting the
operation of my patch to "allow typing `make cc1plus' on second
thought", to languages that are built by default.
I don't like the attached patch particularly, but if Salvatore confirms
that it works around his issue, I can give the necessary testing to the
patch.
