Bug#52514: mysql 5.1 do_abi_check does not compile w/ gcc4.5

due to GCC preprocessor change
      
The problem is that newer GCC versions treats missing headers
as fatal errors. The solution is to use a guard macro to prevent
the inclusion of system headers when checking the ABI with the
C Preprocessor.
