Here is a simple test along the lines of this issue: #if 0 #define A(x) (x) #endif
#if defined(A) && A(1) one #endif Try running the preprocessor on it: % clang -E test.c # 1 "test.c" # 1 "<built-in>" 1 # 1 "<built-in>" 3 # 382 "<built-in>" 3 # 1 "<command line>" 1 # 1 "<built-in>" 2 # 1 "test.c" 2 test.c:5:19: error: function-like macro 'A' is not defined Try it on linux using gcc: % cc -E test.c # 0 "test.c" # 0 "<built-in>" # 0 "<command-line>" # 1 "/usr/include/stdc-predef.h" 1 3 4 # 0 "<command-line>" 2 # 1 "test.c" test.c:5:20: error: missing binary operator before token "(" I think that this preprocessor scheme is flawed.
