It was a Bell labs creation and their f77 'compiler' sort of created an IL 
that was passed to the C compiler. Like making sausage it works great if 
you don't look at the process. If you want readable C code you can modify, 
not so great.

I haven't had a need to did into it but on Linux f77 gets passed to 
gfortran and I think it all ultimately winds up in C++.
