Hi, I would like to write C code such as the following: #define X_MIN -7.5 #define X_MAX 12.7 #define X_STEP 0.1 #define NPOINTS ((unsigned) (X_MAX - X_MIN) / X_STEP)) static int state[NPOINTS]; However, it generates a compiler warning as follows: variably modified 'state' at file scope Such code is compiled without any warning by Microsoft Visual C++ (from as far back as MSVC++ 2008). The above warning is correct, as far as C language definition is concerned (any floating-point constants participating in an integer expression must be immediate operands of casts). Other than the above warning, the resulting executable works as expected. In particular, the size of state is correct in all cases. I am used to being able to suppress any kind of GCC compiler warning by using an appropriate compiler option of pragma. How can the above warning be suppressed? Thanks, Beni Falk
