In ext/fiddle/function.c, Fiddle::Function::STDCALL is defined only when "#ifdef FFI_STDCALL" is true. However, in ffi.h, FFI_STDCALL is declared as an enumerated type, not a macro, and it is always false even on x86 WIN32. According to the Changelog in libffi-3.0.11.tar.gz, FFI_STDCALL was first added in 2002-11-10 as an enumeration.

I create a patch to check existance of FFI_STDCALL in extconf.rb.
