However, the s390x-ibm-tpf example does not use those macros. I can attach a listing, since I doubt that you have this compiler built in place, and it will be apparent that the builtin is behaving improperly, comparing against ascii '0' even though the compiler is translating all character literals into IBM1047. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=18785
