Subject: Re: [Boost-users] [wave] fail to parse variadics macro

Thank you, Hartmut for prompt reply! However, I am not forgetting anything as this definition comes from 'standard' header: see line 36: # define __builtin_warning(x, y...) (1) For a test case, trivial TU will suffice: #include <compiler.h> int main() {     return 0; } Also, here is a description for variadics from GNU docs: , which corresponds with what I came across in compiler.h So, the question is, would wave process line 36 from compiler.h mentioned above the same way gcc process it?

From the error message above I can tell, that you forgot the comma in fromnt of the ellipses:     #define __builtin_warning(x, y, ...) Which will compile just fine.
