severity 488817 serious thanks The problem is | #ifndef __s390x__ | #define __s390x__ 1 | #endif This is broken and comes not from the compiler. Okay, it is done by the following part of configure: | echo "${ECHO_T}$cl_cv_host_x86_64" >&6; } | if test $cl_cv_host_x86_64 = yes; then | host_cpu_instructionset=x86_64 | else | host_cpu_instructionset=i386 | fi | ;; | *) | host_cpu_instructionset=$host_cpu | ;; | esac | cat >> confdefs.h <<EOF | #ifndef __${host_cpu_instructionset}__ | #define __${host_cpu_instructionset}__ 1 | #endif | EOF Anyway, this is so broken that is even fails or produces wrong output on powerpc.
