C powder toy game

I fucking suck at programming.
I am trying to edit the powder toy games source, I had to get the SDL libraries and then after that when I try and build it, I get the error:
C:\Program Files\PellesC\Include\Win\SDL_stdinc.h(218): warning #2016: Use of __declspec(dllexport) requires the /Ze option; ignored.

For each SDL file?
I am using Pelles C for windows, if that matters.

That's because the overwhelming majority of people who use computers, use windows.

Mixing libraries isn't good... You can solve this easily by moving the SDL stuff into a different c file, but that's probably too complex for you.

SDL_config_win32.h(65-68):
#ifndef _SIZE_T_DEFINED_
#define _SIZE_T_DEFINED_
typedef unsigned int size_t;
#endif
