Yes, I confirm that

Here the definition of the function/macro SDL_LoadBMP in SDL_surface.h:

/extern DECLSPEC SDL_Surface *SDLCALL SDL_LoadBMP_RW(SDL_RWops * src,/
/                                                    int freesrc);/

/ *  Load a surface from a file./
/ */
/ *  Convenience macro./
/ *//
/#define SDL_LoadBMP(file)   SDL_LoadBMP_RW(SDL_RWFromFile(file, "rb"), 1)/

.. but, I don't see nothing really strange..

Yes, no problem, I attached the tar.gz file of the project
