Errors building the current trunk

[Damian Rouson <damian at sourceryinstitute dot org>]

All,

In an attempt to develop a patch for the contrib/download_prerequisites script, I cloned the trunk last night and am encountering an error in building gfortran so that I can run the regression tests. The error message is at the bottom of this email.  

My steps were as follows:  

git clone git://gcc.gnu.org/git/gcc.git  
cd gcc
git branch download-prerequisites
git checkout download-prerequisites
./configure --prefix=/opt/gnu/7.0.0/2016-09-23 --enable-languages=c,c++,fortran,lto --disable-multilib --disable-werror
make bootstrap

Could anyone advise me about how to build gfortran successfully? In this case, I was building with GCC 5.4 installed via apt-get on Lubuntu Linux. I also tried building with the trunk itself.
