The string "LINUX" doesn't appear in my subversion WC including build outputs (except for the tests you added), nor anywhere in /usr/include except this one test:

/usr/include/apr-1.0/apr_general.h:#if defined(CRAY) || (defined(__arm) && !defined(LINUX))

"cpp -dM" prints out the preprocessor's predefined macros; it isn't there either:

$ cpp -dM /dev/null | grep LINUX
$ cpp --version
cpp (Ubuntu/Linaro 4.6.1-9ubuntu3) 4.6.1

So where does it come from on your system, and what does it mean?
