Source code of large programs wanted

[Derek M Jones <derek@NOSPAMknosof.co.uk>]

All,

My interest is in measuring source code.
You can can find some of my measurements of C
source at www.knosof.co.uk/cbook/usefigtab.pdf
(you might want to skip to table 26; many of the
tools used are available at
www.knosof.co.uk/cbook/srccnt.tgz).

I would like to measure Ada source and am
looking a selection of large Fortran programs
(i.e., +100K lines per program) for a total of around
3-5 million lines of source.  I don't mind what the
code does, but would prefer a wide selection of
different kinds of application.  I don't plan to
execute the software, so no data-sets are needed.
I would like others to have access to the source
(so they can also measure it), so publicly available
source is needed.  A selection of programs developed
in the 80's, and 90's would be great.

Suggestions most welcome (either the name of the
program or a url will do).
