Re: [PATCH] Choose XDL_FAST_HASH code on sizeof(long) instead of __WORDSIZE

Darwin does not define __WORDSIZE, and compiles the 32-bit code path

I could not find an alternative -- other than the platform symbols
(__x86_64__ etc.) -- that does the test in the preprocessor.  However,
we can also just test for the size of a 'long', which is what really
matters here.  Any compiler worth its salt will leave only the branch
relevant for its platform, and indeed on Linux/GCC the numbers don't
change:

Thanks.
