ambiguous symbol /visual studio/ c code - c++

Question

Hy ,so my project to migrate to Visual Studio 2015. However I got stuck when I saw that receive 13 errors.
Error C2872 'data': ambiguous symbol Error C2872 'size': ambiguous symbol
Before you migrate to vss2015 everything work perfectly, I can not understand why we have moved the program after receiving this error.
Here is my Jpeg.cpp

int jpeg_load_from_mem(unsigned char*_data, int size, unsigned char*dest, int width, int height);
I get the error for "data" and also for "size" symbol.
Best regards.
Why in visual studio 2013 i dont have that this error? And how to solve..
I get ambiguous symbol 10 times, in 10 sintax in jpeg.cpp
