Googling “writing fortran compiler” gets information on using one. The Think in Geek blog has several posts, mostly about flang. Maybe they will be helpful to GSoC students.

I have heard the “old” (PGI-derived) flang referred to as “flung”, while the new (and definitely different) LLVM project referred to as FLANG (in all uppercase, similar to CLANG) to further differentiate. Even PGI/NVIDIA sees the new FLANG compiler as their future direction.
