Where is WIN32 defined, and how can I include this definition in my project?

Question

I am including a third party header and source file into my project.

At the top of the header there is this:

#if defined(WIN32) || defined(WIN16)
#i         


        

Answer 1

Visual Studio has the built-in define _WIN32. mingw-gcc has WIN32 and _WIN32 built-in so the project was likely tested using gcc. You might add

#if defined(_WIN32) && !defined(WIN32)
#define WIN32
#endif

or just add a -DWIN32 to the CFLAGS.
