I thought I had reported this before (maybe just informally). I have been helping myself locally using this: No, the compiler should provide a working "wmmintrin.h" header in one of its built-in paths if it supports the AES instructions. This is akin to saying that code that uses "stdio.h" should use -I/usr/src/include. -- John Baldwin
