To test Josh's hypothesis, you can try compiling with '-U Status', to
undefine any previous definition of that symbol.

E.g., if you're building an executable called 'bookboot', you could
add this line to your CMakeLists.txt:

rosbuild_add_compile_flags(bookboot -U Status)

If that works (with your message still called 'Status'), then you'd
want to track down the #define of 'Status'.
