# note that rffi.INT as first parameter type is intentional.
# on s390x providing a lltype.Signed as param type, the
# macro wrapper function will always return 0
+ # reason: legacy code required a union wait. see
+ # https://sourceware.org/bugzilla/show_bug.cgi?id=19613
+ # for more details. If this get's fixed we can use lltype.Signed
+ # again.
