Message : Test bitstring macro evaluation. For all bitstring macros, add a test with side effects in the arguments. Also fix compiler warnings and wrap long line. In main() replace exit(0) with return(0) to check stack canary. Create expected test files with make target create-good. OK florian deraadt@
