As Chuck pointed out you should use __CYGWIN__ instead of _WIN32 in this case. 
However, I wouuld remove the outer #if. Isn't enought to do:
#if defined(MAKEDLL)
# define INTERFACE __declspec(dllexport)
#elif defined(USEDLL)
# define INTERFACE __declspec(dllimport)
#else
# define INTERFACE
#endif

The community should be using __CYGWIN__ for preprocessor conditioning for the
Cygwin GCC. One of the major problems I have with having the _WIN32 macro
defined is that some software already uses the macro to condition for Win32
specific things and that gets in the way of compiling for POSIX.
