When linking example, I get "Undefined symbol detect_cpu in file scrypt-jane.o" error with gcc 4.5.2 on new sparc64 with Solaris 11. This is how I compile:

gcc scrypt-jane.c -O3 -DSCRYPT_CHACHA -DSCRYPT_KECCAK512 -DSCRYPT_CHOOSE_COMPILETIME -mcpu=v9 -m64
gcc example.c scrypt-jane.o -mcpu=v9 -m64 -o example

If I insert a dummy detect_cpu function that returns 0 in scrypt-jane-portable.h, the code compiles without error, but I get "scrypt: mix function power-on-self-test failed" at program execution.

I am not sure if this library is supposed to work on sparc64 platform.
Are there any compiler flags I am missing?
