It seems users who have Fortran-C-interop code will need to toggle the `-fno-fortran-main` option ON and OFF depends on who the `main` is. I think there are some real issues on AIX as Kelvin mentioned on top of what we have encountered on Linux. However, these issues are not directly related to this PR. Thanks to all for the response and explanation!
