This is what I get on a fresh, default install of cygwin:

$ mpif77

-------
The Open MPI wrapper compiler was unable to find the specific compiler
ifort.exe in your PATH.

Note that this compiler was either specified at configure time or in
one of several possible environment variables.
-------

So for some reason writing mpif77 on the command line does not result on 
a "bash: command not found" error. For some reason the command is
referenced,
even though it doesn't work out of the box.

I installed cyg-apt in the vain hope that it would be able to download open
mpi
or mpich2, but no such luck.
