I looked at the code and couldn't see anything obviously wrong.
Did you get this to work using a PC gcc (for example on Linux)?

I did have trouble compiling this line.

  tiger_compress_macro(((word64*)str), ((word64*)state));

You should step through both the gcc and msvc versions to
see if your intermediate values are being XOR'd, etc.,
correctly. The problem should pop up fairly quickly. You
may want to turn off any optimizations. Also printf'ing
the intermediate unsigned ints in hex from both versions
and then diff'ing could help automate the debugging.
