[SDL] SDL_Image compiler errors on PB2 (OSX)

[Priest]

Hi.
I've got a problem compiling my project (and even a very simple project) 
containing the SDL_Image Framework under OSX (Projectbuilder 2, April).
For example:
- I generate a new "SDL_Application"
- I link the SDL_Image.Framework, (the devel one), placed in 
~/library/frameworks
- I add the header folder path (not the reference, the full path) to 
"Search for headers" in my current target's settings
- I do an #include "SDL_image.h" in the main.c
- I compile

and after this I get PLENTY of errormessages, like

[...]/SDL_image.h:46: illegal external declaration, missing `;' after 
`SDLCALL'

Which refers to the following line:

extern DECLSPEC SDL_Surface * SDLCALL IMG_LoadTyped_RW(SDL_RWops *src, 
int freesrc, char *type);

Well, this is the nice version, in my project (which is c++) I simply get
error before "("

Any idea how to fix this?
