a cutdown test case that shows the gcc 4.7 error

Trying to build llvm with gcc 4.7
fails due to a cast-qual warning message cum error message
getting an -Wcast-qual -Werror

Compilation line is,

-I/site/spt/usr7/XXX/bug/llvm-3.1.src/include
-I/site/spt/usr7/XXX/bug/llvm-3.1.src/lib/CodeGen -D_DEBUG -D_GNU_SOURCE
