Hello,

I was trying to compile pieces of CGAL code under windows 7 with MinGW 64 to 
build a R package with alpha_shapes_3 computation.
I am compiling with undefined GMP, MPFR, GMPXX, ... (please refer to my 
compiler_config.h file).

I have the following error:
./CGAL/double.h:132:10: error: 'CGAL_ALIGN_16' does not name a type

because in config.h (_M_X64 is defined with MinGW64):
#if (_M_IX86_FP >= 2) || defined(_M_X64)
#define CGAL_USE_SSE2_FABS
#endif

but in sse2.h:
#if defined ( _MSC_VER )
#define CGAL_ALIGN_16  __declspec(align(16))
#elif defined( __GNU__ )
#define  CGAL_ALIGN_16 __attribute__((aligned(16))) 
#endif

With MinGW64, _MSC_VER and __GNU__ are not defined.

I modified sse2.h like this to make it compile:
#if defined ( _MSC_VER )
#define CGAL_ALIGN_16  __declspec(align(16))
#elif defined( __GNU__ )
#define  CGAL_ALIGN_16 __attribute__((aligned(16))) 
#elif defined( __MINGW64__ )
#define  CGAL_ALIGN_16 __attribute__((aligned(16))) 
#endif

I was wondering to know if this is the good way to work-around my issue ?

Thanks in advance,

Vincent Rouvreau
