Can anyone explain what this in is about: #ifndef __dj_include_math_h_ #define __dj_include_math_h_ #ifdef _USE_LIBM_MATH_H #include #else /* All of the header file goes here. */ #endif /* _USE_LIBM_MATH_H */ #endif /* !__dj_include_math_h_ */ Now when (soon i. e.) isnan() and isinf() is in libc and is updated, I think libm should be converted to used them. libm's makefile #defines _USE_LIBM_MATH_H. What should be done? Should be updated according to ? Right, MartinS
