Errors in stdio.h when compiling mex program with Microsoft Visual C++ 2017 Compiler

I had previously compiled my project with the MinGW C compiler successfully. Now I want to be able to debug it and so I followed instructions here:https://www.mathworks.com/help/matlab/matlab_external/debugging-on-microsoft-windows-platforms.html

I have installed Visual Studio Professional 2017 (free trial).

Afterwards I tried to compile with this command:

mex -g -R2018a memMap.c mapping.c fileHelper.c numberHelper.c queue.c mman.c

, and got this error:

Building with 'Microsoft Visual C++ 2017 (C)'.
Error using mex
memMap.c
d:\work\matfile-parsing\v7.3files\mapping.h(7): fatal error C1083: Cannot open include file: 'unistd.h': No such file or directory

So I tried adding the path to the unistd.h header file:

mex -g -R2018a -IC:\MinGW\include memMap.c mapping.c fileHelper.c numberHelper.c queue.c mman.c

and got many errors, all in header files that used to compile with the MinGW compiler:

How can I fix this? I am using MATLAB R2018b.

[CB]

I fixed this by putting all of my code into a visual studio c++ project and compiling it from there. This let me see different errors that I couldn't see in matlab. After fixing these, I was able to remove the -I portion of the compilation command and compilation succeeded.
