gfortran can handle F90 and F77, but in your makefile
you have no rule for ".f90" extension

Why gcc is invoked for Fortran ??
See "10.7 Old-Fashioned Suffix Rules" of info make

The message is clear. You gave no indication how to make
swan_init.o from swan_init.f90
Try to copy/rename the swan_init.f90 to swan_init.f
and see what happens

during the linking you need to add the
"-lgfortranbegin -lgfortran"

No. it compiles also F77

I doubt

This is not really a cygwin problem.
You should read the make documentation.
