What's the error? Is it caused by re-declaration with a different calling convention i.e. `__stdcall` vs. `__cdecl`?
I'm therefore looking for a portable way of detecting whether the compiler is a mingw-w64 one && the Windows implementation of those 2 functions has been found.
This issue is not specific to mingw-w64. If MSVC was used to build Perl, there would be the same error, because we do the same.
My suggestion is to check for the macro `InetNtopA` like this: ``` #ifdef InetNtopA /* Windows-specific stuff here. */ #else /* Linux, BSD, etc. */ #endif ``` -- Best regards, LIU Hao
