I had thought that after some point (say, f77) the practical thing was to

mistaken.
Compilers are designed to compile code written by humans.
Autogenerated code typically does not optimize well.
Or be human-readable. f2c code was just about as evil as any zomby
woof or eskimo boy could be. I used to try to use it to START porting
fortran sources to C, but rapidly concluded that it was actually easier
and saner to just rewrite the algorithms in native C by hand. It was a
really educational experience for those that would assert that fortran
is "just like" C on the back end, though -- "just like" is well defined
by the required compatibility libraries and stuff that has to be done to
convert data structures. They were not, not, not pretty...
