Enable Portable word Size option generating wrong include in the code.

Hello,

I am using the option Enable Portable Word Size option in the Configuration and it is creating a worng include in the code file.

In 2013b it is generating a wrong include but when i checked in R2018b it generates a correct inlude.

R2013b:

R2018b:

Is there some patch available so that the issue can be fixed in R2013b as well.

we have huge number of models generated in R2013b.
