Suspected Memory Size Problems under Cygwin

I have a Fortran code, developed mostly under Unix/Linux. In the past (years ago) I have compiled it under Cygwin and run it with no problems. I am now adding some more stuff to it and the user was wanting to run it under Cygwin. So I compile it no problem, but then when I execute it -- noth

Poor execution speeds using -mno-cygwin g77 option

I am experiencing significantly longer exection speeds when compiling with g77 under cygwin using the -mno-cygwin option. I primarily work and develop under Linux. However, I need to provide a user with an executable (of a Fortran program) that runs under windows. I initially performed some t
