Do the above 9 lines or 80 lines include the entire prerequisite software
stack or just the ones that the download_prerequisites script downloads?
If I recall correctly, building gfortran also requires flex and building
flex requires bison and building bison requires m4 and the
download_prerequisites script didn't download any of those the last time I
checked.

I realize that building gfortran from source comes very easily to GCC
developers, especially if they do it regularly.  I've encountered a lot of
people who found it challenging, including myself initially, which was the
reason for incorporating the capability into the OpenCoarrays installer.
