Doesn't build on Snow Leopard 10.6

Originally reported on Google Code with ID 154

What steps will reproduce the problem?
1. Checkout latest sources (r174596)
2. Build using cmake and clang binaries from (http://www.llvm.org/releases/download.html#3.2)

export DEST_CLANG=/tmp/clang; mkdir cbuild && (cd cbuild && CC=~/clang3.2/bin/clang
CXX=~/clang3.2/bin/clang++ cmake -DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_ASSERTIONS=OFF
-DCMAKE_INSTALL_PREFIX=$DEST_CLANG ../ && make -j2)

 you get the 2 errors for undefined type :

What is the expected output? What do you see instead?

It should compile.

What version of the product are you using? On what operating system?

$ uname -a
Darwin Host.local 10.8.0 Darwin Kernel Version 10.8.0: Tue Jun  7 16:33:36 PDT 2011;

===========================

Same issue with 'stock' GCC (4.2)

========= CURRENT SOLUTION =======

change the cmake commandline into :

CC=~/clang3.2/bin/clang CXX=~/clang3.2/bin/clang++ CFLAGS="-D_FILE_OFFSET_BITS=64"
CXXFLAGS="-D_FILE_OFFSET_BITS=64" cmake -DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_ASSERTIONS=OFF
-DCMAKE_INSTALL_PREFIX=$DEST_CLANG ../ 

and patch the interception_type_test.cc like this :

If there is no off64_t on Mac, we should just skip the test.
I hope my latest change fixed this.

Thanks. With latest ToT (r174701), it works for me
