Obviously.  But I doubt that wProcessorLevel is what's needed here.
Isn't there something like wProcessorArchitecture that distinguishes
between 32 and 64 bit?
seems so. I will check this weekend .

It should be fixed,
we have now more PROCESSOR_ARCHITECTURE :
+    case PROCESSOR_ARCHITECTURE_AMD64:
+        strcpy(uts->machine, "amd64");
+        break;
+    case PROCESSOR_ARCHITECTURE_ARM:
+        strcpy(uts->machine, "arm");
+        break;
+    case PROCESSOR_ARCHITECTURE_ARM64:
+        strcpy(uts->machine, "arm64");
+        break;
+    case PROCESSOR_ARCHITECTURE_IA64:
+        strcpy(uts->machine, "ia64");
+        break;
Thank you Luigi!
Currently I get "x86_64" on Linux.  Will it be sufficient check
whether the string ends with '64' in order to determine reliably
whether I'm on a 64 bit machine?  That would be nice because
conditional code or table lookups can be avoided.
hm, what we have now  ( always   #ifdef _WIN32   is true ) is :

    switch (sysinfo.wProcessorArchitecture) {
    case PROCESSOR_ARCHITECTURE_AMD64:
        strcpy(uts->machine, "amd64");
        break;
    case PROCESSOR_ARCHITECTURE_ARM:
        strcpy(uts->machine, "arm");
        break;
    case PROCESSOR_ARCHITECTURE_ARM64:
        strcpy(uts->machine, "arm64");
        break;
    case PROCESSOR_ARCHITECTURE_IA64:
        strcpy(uts->machine, "ia64");
        break;
    case PROCESSOR_ARCHITECTURE_PPC:
        strcpy(uts->machine, "ppc");
        break;
    case PROCESSOR_ARCHITECTURE_ALPHA:
        strcpy(uts->machine, "alpha");
        break;
    case PROCESSOR_ARCHITECTURE_MIPS:
        strcpy(uts->machine, "mips");
        break;
    case PROCESSOR_ARCHITECTURE_INTEL:
        /*
         * dwProcessorType is only valid in Win95 and Win98 and WinME
         * wProcessorLevel is only valid in WinNT
         */
        switch (os) {
        case Win95:
        case Win98:
            switch (sysinfo.dwProcessorType) {
            case PROCESSOR_INTEL_386:
            case PROCESSOR_INTEL_486:
            case PROCESSOR_INTEL_PENTIUM:
                sprintf(uts->machine, "i%ld", sysinfo.dwProcessorType);
                break;
            default:
                strcpy(uts->machine, "i386");
                break;
            }
            break;
        case WinNT:
            sprintf(uts->machine, "i%d86", sysinfo.wProcessorLevel);
            break;
        default:
            strcpy(uts->machine, "unknown");
            break;
        }
        break;
    default:
        strcpy(uts->machine, "unknown");
        break;
    }
