Commit Message

_Bool needs to be defined as macro in order to trigger the
context-sensitive macro expansion mechanism.

Bootstrapped and regtested on s390x.

Committed to mainline.

gcc/ChangeLog:

	* config/s390/s390-c.c (s390_cpu_cpp_builtins_internal): Define
	_Bool as macro expanding to _Bool.

gcc/testsuite/ChangeLog:

	* gcc.target/s390/zvector/vec-_Bool.c: New test.
