- check defines and includes used at compile time and if different

   force rebuilding everything in the current dir (creates a new file:
   makecfg.lst that stores the compile defines & includes used at compile
   time). This should solve problems such as compiling mysql with malloc
  debugging, modifiyng a file and then recompiling without malloc debugging.
