Check init.c, which is #included (yuck) in dllcrt1.c. If you like you can remove the declarations from stdlib.h and work up a DLL version of init.c to remove the dependency of your DLL on the C run-time library. (I suspect this hasn't changed in Mumit's version, I must admit I only checked my source.) I suppose the other reason I didn't worry much about this was that I wasn't expecting people to write much DLL code without calling any C library functions.
