error #5149: Illegal character in statement label field with matlab2016b

I am trying to compile a fortran mex file which is associated with a matlab code. I ran the command ‘mex FileName.f90’ on Matlab 16b and it gave me the “error #5149: Illegal character in statement label field”. I am using Matlab 16b and Intel Parallel Studio XE 2016 for Fortran with Microsoft Visual Studio 2013. I tried to remove the /fixed from mexopts folder as suggested by several posts but still get the same error. Can someone help me to solve the issue? I am quite new to programming. Thank you Prasanna
