>Description:
Macro _POSIX_THREADS indicates presense of POSIX threads at compile
time. sysconf(_SC_THREADS) should be used to check whether POSIX
threads is available at runtime. However, code using _SC_THREADS
fail to compile because _SC_THREADS does not exist.
>How-To-Repeat:
#include <unistd.h>
#include <stdio.h>
int
main()
{
#ifdef _POSIX_THREADS
printf("sysconf(_SC_THREADS): %d\n", sysconf(_SC_THREADS));
#else
printf("_POSIX_THREADS not defined\n");
#endif
return 0;
