Comment (by ballapete):

 Changing the block to

 {{{
 static unsigned
 GetCPUCount()
 {
     static unsigned ncpus = 0;
     if (ncpus == 0) {
 # ifdef XP_WIN
         SYSTEM_INFO sysinfo;
         GetSystemInfo(&sysinfo);
         ncpus = unsigned(sysinfo.dwNumberOfProcessors);
 # elif __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__ < 1050
         long n = sysconf(HW_NCPU);
         ncpus = (n > 0) ? unsigned(n) : 1;
 # else
         long n = sysconf(_SC_NPROCESSORS_ONLN);
         ncpus = (n > 0) ? unsigned(n) : 1;
 # endif
     }
     return ncpus;
 }
 #endif /* JS_THREADSAFE */
 }}}

 should work – but sys/sysctl.h is never included! Maybe sys/sysctl.h could
 be included here:

 {{{
    96   #ifdef XP_WIN
    97   # include "jswin.h"
    98   #else
    99   # include <unistd.h>
   100   #endif
 }}}
