It means that assembler alone won't do preprocessing. Right. The C preprocessor is not normally used for assembler, and for the x86 assembler (and other targets) the # character starts a comment. > But c or c++ alone does preprocessing(they did not define c-with-cpp)!! Of course, the preprocessor is a required phase in the processing of standard C and C++ source code. > and another thing is f95-cpp-input, does it mean like assembler-with-cpp? I believe so. Again, the C preprocessor is not a standard step in compiling Fortran code, see http://gcc.gnu.org/onlinedocs/gfortran/Preprocessing-and-conditional-compilation.html
