gcc was configured with

../../gcc/trunk/configure --enable-languages=c,fortran --prefix=$HOME --enable-maintainer-mode --disable-multilib

(Shouldn't there be a libiberty component?)

This is a bit of a nuisance because I can't test other

I have a dded dj to the CC because he was last to touch that
directory.

I've added dj to the CC list because he was the last one to touch that directory.

After the "make info", I get
