The Cygwin Fortran package is gcc-fortran (gfortran/f95 symlink): you should see 
this unless you have been using a proprietary closed source compiler.
It looks like Dislin is a proprietary closed source plotting package which you 
will have to find, acquire, install, and configure separately, or migrate 
settings from your old system.
