So if I run a valgrind enabled gcc trunk over the C, C++ and Fortran
code in the testsuite once a week, then that should match your testing
activity.

There are about 5,800 Fortran source code files, about 16,100 C++
and about 35,800 C source code files. That's a lot.=20

I'll start with Fortran, then add in C++ then C and see how I get on.=
